Description
The CoolSET®-F3R FullPak is the enhanced version of
CoolSET®-F3 and targets for the Off-Line Adapters and
high power range SMPS in DVD R/W, DVD Combi, set top
box, etc. It has a wide Vcc range to 25V by adopting the
BiCMOS technology. With the merit of Active Burst Mode, it
can achieve the lowest Standby Power Requirements
(<100mW) at no load and Vin = 270VAC. Since the
controller is always active during the Active Burst Mode, it
is an immediate response on load jumps and leads to <1%
voltage ripple voltage at output. In case of protection for
Overtemperature, Overvoltage, Open loop and Overload
conditions, it would enter Auto Restart Mode. Thanks for the
internal precise peak current limitation, it can provide
accurate information to optimize the dimension of the
transformer and the output diode. The built-in blanking
window can provide sufficient buffer time before entering
the Auto Restart Mode. In case of longer blanking time, a
simply addition of capacitor to BA pin can serve the
purpose. Furthermore, the built-in frequency jitter function
can effectively reduce the EMI noise and further reduce the
scale of input filter. The component counts can further be
reduced with the various built-in functions such as soft start,
blanking time and frequency jitter.

1.2 Pin Functionality
Drain (Drain of integrated CoolMOS®)
Pin Drain is the connection to the Drain of the internal
CoolMOS®and the HV of the startup cell.
CS (Current Sense)
The Current Sense pin senses the voltage developed
on the series resistor inserted in the source of the
integrated CoolMOS®. If CS voltage reaches the
internal threshold of the Current Limit Comparator, the
Driver output is immediately switched off. Furthermore
the current information is provided for the PWM-
Comparator to realize the Current Mode.
BA (extended Blanking & Auto-restart enable)
The BA pin combines the functions of extendable
blanking time for over load protection and the external
auto-restart enable. The extendable blanking time
function is to extend the built-in 20 ms blanking time by
adding an external capacitor at BA to ground. The
external auto-restart enable function is an external
access to stop the gate switching and force the IC to
enter auto-restart mode. It is triggered by pulling down
the BA pin to less than 0.33V.
VCC (Power Supply)
The VCC pin is the positive supply of the IC. The
operating range is between 10.5V and 25V.
GND (Ground)
The GND pin is the ground of the controller.
FB (Feedback)
The information about the regulation is provided by the
FB Pin to the internal Protection Unit and to the internal
PWM-Comparator to control the duty cycle. The FB-
Signal is the only control signal in case of light load at
the Active Burst Mode.

Functional Description
3 Functional Description
All values which are used in the functional description
are typical values. For calculating the worst cases the
min/max values which can be found in section 4
Electrical Characteristics have to be considered.
3.1 Introduction
CoolSET®-F3R FullPak is the further development of
the CoolSET®-F3 for high power application. The
particular enhanced features are built-in features for
soft start, blanking window and frequency jitter. It also
provides the flexibility to increase the blanking window
by simply adding capacitance in BA pin. However, the
proven outstanding features in CoolSET®-F3 are
remained.
The intelligent Active Burst Mode at Standby Mode can
effectively obtain the lowest Standby Power at
minimum load and no load condition. After entering the
burst mode, there is still a full control of the power
conversion by the secondary side via the same
optocoupler that is used for the normal PWM control.
The response on load jumps is optimized. The voltage
ripple on Vout is minimized. Vout is on well controlled in
this mode.
The usually external connected RC-filter in the
feedback line after the optocoupler is integrated in the
IC to reduce the external part count.
Furthermore a high voltage Startup Cell is integrated
into the IC which is switched off once the Undervoltage
Lockout on-threshold of 18V is exceeded. This Startup
Cell is part of the integrated CoolMOS®. The external
startup resistor is no longer necessary as this Startup
Cell is connected to the Drain. Power losses are
therefore reduced. This increases the efficiency under
light load conditions drastically.
This version is adopting the BiCMOS technology and it
can increase design flexibility as the Vcc voltage range
is increased to 25V.
For this full package version, the soft start is a built-in
function. It is set at 20ms. Then it can save external
component counts.
There are 2 modes of blanking time for high load
jumps; the basic mode and the extendable mode. The
blanking time for the basic mode is pre-set at 20ms
while the extendable mode will increase the blanking
time at basic mode by adding external capacitor at the
BA pin. During this time window the overload detection
is disabled. With this concept no further external
components are necessary to adjust the blanking
window.
In order to increase the robustness and safety of the
system, the IC provides Auto Restart protection mode.
The Auto Restart Mode reduces the average power
conversion to a minimum under unsafe operating
conditions. This is necessary for a prolonged fault
condition which could otherwise lead to a destruction of
the SMPS over time. Once the malfunction is removed,
normal operation is automatically recovered after the
next Start Up Phase.
The internal precise peak current limitation reduces the
costs for the transformer and the secondary diode. The
influence of the change in the input voltage on the
power limitation can be avoided together with the
integrated Propagation Delay Compensation.
Therefore the maximum power is nearly independent
on the input voltage which is required for wide range
SMPS. There is no need for an extra over-sizing of the
SMPS, e.g. the transformer or the secondary diode.
Furthermore, this full package version implements the
frequency jitter mode to the switching clock such that
the EMI noise will be effectively reduced.
3.2 Power Management
Figure 3 Power Management
The Undervoltage Lockout monitors the external
supply voltage VVCC. When the SMPS is plugged to the
main line the internal Startup Cell is biased and starts
to charge the external capacitor CVCC which is
connected to the VCC pin. This VCC charge current is
controlled to 0.9mA by the Startup Cell. When the VVCC
exceeds the on-threshold VCCon=18V the bias circuit
are switched on. Then the Startup Cell is switched off
by the Undervoltage Lockout and therefore no power

losses present due to the connection of the Startup Cell
to the Drain voltage. To avoid uncontrolled ringing at
switch-on a hysteresis start up voltage is implemented.
The switch-off of the controller can only take place after
Active Mode was entered and VVCC falls below 10.5V.
The maximum current consumption before the
controller is activated is about 150mA.
When VVCC falls below the off-threshold VCCoff=10.5V,
the bias circuit is switched off and the soft start counter
is reset. Thus it is ensured that at every startup cycle
the soft start starts at zero.
The internal bias circuit is switched off if Auto Restart
Mode is entered. The current consumption is then
reduced to 250mA.
Once the malfunction condition is removed, this block
will then turn back on. The recovery from Auto Restart
Mode does not require re-cycling the AC line.
When Active Burst Mode is entered, the internal Bias is
switched off most of the time in order to reduce the
current consumption below 500mA.
3.3 Improved Current Mode
Figure 4 Current Mode
Current Mode means the duty cycle is controlled by the
slope of the primary current. This is done by comparing
the FB signal with the amplified current sense signal.
Figure 5 Pulse Width Modulation
In case the amplified current sense signal exceeds the
FB signal the on-time ton of the driver is finished by
resetting the PWM-Latch (see Figure 5).
The primary current is sensed by the external series
resistor RSense inserted in the source of the integrated
CoolMOS®. By means of Current Mode regulation, the
secondary output voltage is insensitive to the line
variations. The current waveform slope will change with
the line variation, which controls the duty cycle.
The external RSense allows an individual adjustment of
the maximum source current of the integrated
CoolMOS®.
To improve the Current Mode during light load
conditions the amplified current ramp of the PWM-OP
is superimposed on a voltage ramp, which is built by
the switch T2, the voltage source V1 and a resistor R1
(see Figure 6). Every time the oscillator shuts down for
maximum duty cycle limitation the switch T2 is closed
by VOSC. When the oscillator triggers the Gate Driver,
T2 is opened so that the voltage ramp can start.
In case of light load the amplified current ramp is too
small to ensure a stable regulation. In that case the
Voltage Ramp is a well defined signal for the
comparison with the FB-signal. The duty cycle is then
controlled by the slope of the Voltage Ramp.
By means of the time delay circuit which is triggered by
the inverted VOSC signal, the Gate Driver is switched-off
until it reaches approximately 156ns delay time (see
Figure 7). It allows the duty cycle to be reduced
continuously till 0% by decreasing VFB below that
threshold.

3.3.1 PWM-OP
The input of the PWM-OP is applied over the internal
leading edge blanking to the external sense resistor
RSense connected to pin CS. RSense converts the source
current into a sense voltage. The sense voltage is
amplified with a gain of 3.3 by PWM OP. The output of
the PWM-OP is connected to the voltage source V1.
The voltage ramp with the superimposed amplified
current signal is fed into the positive inputs of the PWM-
Comparator C8 and the Soft-Start-Comparator (see
Figure 6).
3.3.2 PWM-Comparator
The PWM-Comparator compares the sensed current
signal of the integrated CoolMOS®with the feedback
signal VFB (see Figure 8). VFB is created by an external
optocoupler or external transistor in combination with
the internal pull-up resistor RFB and provides the load
information of the feedback circuitry. When the
amplified current signal of the integrated CoolMOS®
exceeds the signal VFB the PWM-Comparator switches
off the Gate Driver.

3.4 Startup Phase
Figure 9 Soft Start
In the Startup Phase, the IC provides a Soft Start
period to control the primary current by means of a duty
cycle limitation. The Soft Start function is a built-in
function and it is controlled by an internal counter.
.
Figure 10 Soft Start Phase
When the VVCC exceeds the on-threshold voltage, the
IC starts the Soft Start mode (see Figure 10).
The function is realized by an internal Soft Start
resistor, an current sink and a counter. And the
amplitude of the current sink is controlled by the
counter (see Figure 11).
Figure 11 Soft Start Circuit
After the IC is switched on, the VSOFTS voltage is
controlled such that the voltage is increased step-
wisely (32 steps) with the increase of the counts. The
Soft Start counter would send a signal to the current
sink control in every 600us such that the current sink
decrease gradually and the duty ratio of the gate drive
increases gradually. The Soft Start will be finished in
20ms (tSoft-Start) after the IC is switched on. At the end of
the Soft Start period, the current sink is switched off.

Within the soft start period, the duty cycle is increasing
from zero to maximum gradually (see Figure 12).
In addition to Start-Up, Soft-Start is also activated at
each restart attempt during Auto Restart.
Figure 13 Start Up Phase
The Start-Up time tStart-Up before the converter output
voltage VOUT is settled, must be shorter than the Soft-
Start Phase tSoft-Start (see Figure 13).
By means of Soft-Start there is an effective
minimization of current and voltage stresses on the
integrated CoolMOS®, the clamp circuit and the output
overshoot and it helps to prevent saturation of the
transformer during Start-Up.
3.5 PWM Section
Figure 14 PWM Section Block
3.5.1 Oscillator
The oscillator generates a fixed frequency of 67KHz
with frequency jittering of ±4% (which is ±2.7KHz) at a
jittering period of 4ms.
A capacitor, a current source and current sink which
determine the frequency are integrated. The charging
and discharging current of the implemented oscillator
capacitor are internally trimmed, in order to achieve a
very accurate switching frequency. The ratio of
controlled charge to discharge current is adjusted to
reach a maximum duty cycle limitation of Dmax=0.75.
Once the Soft Start period is over and when the IC goes
into normal operating mode, the switching frequency of
the clock is varied by the control signal from the Soft
Start block. Then the switching frequency is varied in
range of 67KHz ± 2.7KHz at period of 4ms.
3.5.2 PWM-Latch FF1
The output of the oscillator block provides continuous
pulse to the PWM-Latch which turns on/off the internal
CoolMOS®. After the PWM-Latch is set, it is reset by
the PWM comparator, the Soft Start comparator or the
Current -Limit comparator. When it is in reset mode, the
output of the driver is shut down immediately.

3.5.3 Gate Driver
Figure 15 Gate Driver
The driver-stage is optimized to minimize EMI and to
provide high circuit efficiency. This is done by reducing
the switch on slope when exceeding the internal
CoolMOS®threshold. This is achieved by a slope
control of the rising edge at the driver’s output (see
Figure 9).
Figure 16 Gate Rising Slope
Thus the leading switch on spike is minimized.
Furthermore the driver circuit is designed to eliminate
cross conduction of the output stage.
During power up, when VCC is below the undervoltage
lockout threshold VVCCoff, the output of the Gate Driver
is set to low in order to disable power transfer to the
secondary side.
3.6 Current Limiting
Figure 17 Current Limiting Block
There is a cycle by cycle peak current limiting operation
realized by the Current-Limit comparator C10. The
source current of the integrated CoolMOS®is sensed
via an external sense resistor RSense. By means of
RSense the source current is transformed to a sense
voltage VSense which is fed into the pin CS. If the voltage
VSense exceeds the internal threshold voltage Vcsth, the
comparator C10 immediately turns off the gate drive by
resetting the PWM Latch FF1.
A Propagation Delay Compensation is added to
support the immediate shut down of the integrated
CoolMOS®with very short propagation delay. Thus the
influence of the AC input voltage on the maximum
output power can be reduced to minimal.
In order to prevent the current limit from distortions
caused by leading edge spikes, a Leading Edge
Blanking is integrated in the current sense path for the
comparators C10, C12 and the PWM-OP.
The output of comparator C12 is activated by the Gate
G10 if Active Burst Mode is entered. When it is
activated, the current limiting is reduced to 0.26V. This
voltage level determines the maximum power level in
Active Burst Mode.

3.6.1 Leading Edge Blanking
Figure 18 Leading Edge Blanking
Whenever the internal CoolMOS®is switched on, a
leading edge spike is generated due to the primary-
side capacitances and reverse recovery time of the
secondary-side rectifier. This spike can cause the gate
drive to switch off unintentionally. In order to avoid a
premature termination of the switching pulse, this spike
is blanked out with a time constant of tLEB = 220ns.
3.6.2 Propagation Delay Compensation
In case of overcurrent detection, there is always
propagation delay to switch off the internal CoolMOS®.
An overshoot of the peak current Ipeak is induced to the
delay, which depends on the ratio of dI/dt of the peak
current (see Figure 19).
Figure 19 Current Limiting
The overshoot of Signal2 is larger than of Signal1 due
to the steeper rising waveform. This change in the
slope is depending on the AC input voltage.
Propagation Delay Compensation is integrated to
reduce the overshoot due to dI/dt of the rising primary
current. Thus the propagation delay time between
exceeding the current sense threshold Vcsth and the
switching off of the integrated CoolMOS®is
compensated over temperature within a wide range.
Current Limiting is then very accurate.
For example, Ipeak = 0.5A with RSense = 2. The current
sense threshold is set to a static voltage level Vcsth=1V
without Propagation Delay Compensation. A current
ramp of dI/dt = 0.4A/µs, or dVSense/dt = 0.8V/µs, and a
propagation delay time of tPropagation Delay =180ns leads
to an Ipeak overshoot of 14.4%. With the propagation
delay compensation, the overshoot is only around 2%
(see Figure 20).
Figure 20 Overcurrent Shutdown
The Propagation Delay Compensation is realized by
means of a dynamic threshold voltage Vcsth (see Figure
21). In case of a steeper slope the switch off of the
driver is earlier to compensate the delay.

Mode and Auto Restart Mode. The Active Burst Mode

external capacitor at BA pin. By means of this Blanking
Time, the IC avoids entering into these two modes
accidentally. Furthermore those buffer time for the
overload detection is very useful for the application that
works in low current but requires a short duration of
high current occasionally.
3.7.1 Basic and Extendable Blanking Mode
Figure 22 Basic and Extendable Blanking Mode
There are 2 kinds of Blanking mode; basic mode and
the extendable mode. The basic mode is just an
internal pre-set 20ms blanking time while the
extendable mode has extra blanking time by
connecting an external capacitor to the BA pin in
addition to the pre-set 20ms blanking time. For the
extendable mode, the gate G5 is blocked even though
the 20ms blanking time is reached if an external
capacitor CBK is added to BA pin. While the 20ms
blanking time is passed, the switch S1 is opened by
G2. Then the 0.9V clamped voltage at BA pin is
charged to 4.0V through the internal IBK constant
current. Then G5 is enabled by comparator C3. After
the 30us spike blanking time, the Auto Restart Mode is
activated.
For example, if CBK = 0.22uF, IBK = 13.5uA
Blanking time = 20ms + CBK x (4.0 - 0.9) / IBK = 70ms
In order to make the startup properly, the maximum CBK
capacitor is restricted to less than 0.65uF.
The Active Burst Mode has basic blanking mode only
while the Auto Restart Mode has both the basic and the
extendable blanking mode.
3.7.2 Active Burst Mode
The IC enters Active Burst Mode under low load
conditions. With the Active Burst Mode, the efficiency
increases significantly at light load conditions while still
maintaining a low ripple on VOUT and a fast response on
load jumps. During Active Burst Mode, the IC is
controlled by the FB signal. Since the IC is always
active, it can be a very fast response to the quick
change at the FB signal. The Start up Cell is kept OFF
in order to minimize the power loss.
Figure 23 Active Burst Mode
The Active Burst Mode is located in the Control Unit.
Figure 23 shows the related components.
3.7.2.1 Entering Active Burst Mode
The FB signal is kept monitoring by the comparator C5.
During normal operation, the internal blanking time
counter is reset to 0. When FB signal falls below 1.22V,
it starts to count. When the counter reach 20ms and FB
signal is still below 1.22V, the system enters the Active
Burst Mode. This time window prevents a sudden
entering into the Active Burst Mode due to large load
jumps.

Functional Description
Version 2.1 16 7 May 2011
After entering Active Burst Mode, a burst flag is set and
the internal bias is switched off in order to reduce the
current consumption of the IC to approx. 500uA.
It needs the application to enforce the VCC voltage
above the Undervoltage Lockout level of 10.5V such
that the Startup Cell will not be switched on
accidentally. Or otherwise the power loss will increase
drastically. The minimum VCC level during Active Burst
Mode depends on the load condition and the
application. The lowest VCC level is reached at no load
condition.
3.7.2.2 Working in Active Burst Mode
After entering the Active Burst Mode, the FB voltage
rises as VOUT starts to decrease, which is due to the
inactive PWM section. The comparator C6a monitors
the FB signal. If the voltage level is larger than 3.6V, the
internal circuit will be activated; the Internal Bias circuit
resumes and starts to provide switching pulse. In
Active Burst Mode the gate G10 is released and the
current limit is reduced to 0.26V. In one hand, it can
reduce the conduction loss and the other hand, it can
reduce the audible noise. If the load at VOUT is still kept
unchanged, the FB signal will drop to 3.1V. At this level
the C6b deactivates the internal circuit again by
switching off the internal Bias. The gate G11 is active
again as the burst flag is set after entering Active Burst
Mode. In Active Burst Mode, the FB voltage is changing
like a saw tooth between 3.1V and 3.6V (see figure 17).
3.7.2.3 Leaving Active Burst Mode
The FB voltage will increase immediately if there is a
high load jump. This is observed by the comparator C4.
As the current limit is appr. 26% during Active Burst
Mode, a certain load jump is needed so that the FB
signal can exceed 4.5V. At that time the comparator C4
resets the Active Burst Mode control which in turn
blocks the comparator C12 by the gate G10. The
maximum current can then be resumed to stabilize
VOUT.

3.7.3 Protection Modes
The IC provides Auto Restart Mode as the protection
feature. Auto Restart mode can prevent the SMPS from
destructive states. The following table shows the
relationship between possible system failures and the
chosen protection modes.
Before entering the Auto Restart protection mode,
some of the protections can have extended blanking
time to delay the protection and some needs to fast
react and will go straight to the protection. Overload
and open loop protection are the one can have
extended blanking time while Vcc Overvoltage, Over
temperature, Vcc Undervoltage, short opto-coupler
and external auto restart enable will go to protection
right away.
After the system enters the Auto-restart mode, the IC
will be off. Since there is no more switching, the Vcc
voltage will drop. When it hits the Vcc turn off threshold,
the start up cell will turn on and the Vcc is charged by
the startup cell current to Vcc turn on threshold. The IC
is on and the startup cell will turn off. At this stage, it will
enter the startup phase (soft start) with switching
cycles. After the Start Up Phase, the fault condition is
checked. If the fault condition persists, the IC will go to
auto restart mode again. If, otherwise, the fault is
removed, normal operation is resumed.
3.7.3.1 Auto Restart mode with extended
blanking time
Figure 25 Auto Restart Mode
In case of Overload or Open Loop, the FB exceeds
4.5V which will be observed by comparator C4. Then
the internal blanking counter starts to count. When it
reaches 20ms, the switch S1 is released. Then the
clamped voltage 0.9V at VBA can increase. When there
is no external capacitor CBK connected, the VBA will
reach 4.0V immediately. When both the input signals at
AND gate G5 is positive, the Auto Restart Mode will be
activated after the extra spike blanking time of 30us is
elapsed. However, when an extra blanking time is
needed, it can be achieved by adding an external
capacitor, CBK. A constant current source of IBK will start
to charge the capacitor CBK from 0.9V to 4.0V after the
switch S1 is released. The charging time from 0.9V to
4.0V are the extendable blanking time. If CBK is 0.22uF
and IBK is 13.5uA, the extendable blanking time is
around 50ms and the total blanking time is 70ms. In
combining the FB and blanking time, there is a blanking
window generated which prevents the system to enter
Auto Restart Mode due to large load jumps.

3.7.3.2 Auto Restart without extended blanking
time
Figure 26 Auto Restart mode
There are 2 modes of VCC overvoltage protection; one
is during soft start and the other is at all conditions.
The first one is VVCC voltage is > 20.7V and FB is > 4.5V
and during soft_start period and the IC enters Auto
Restart Mode. The VCC voltage is observed by
comparator C1. The fault conditions are to detect the
abnormal operating during start up such as open loop
during light load start up, etc. The logic can eliminate
the possible of entering Auto Restart mode if there is a
small voltage overshoots of VVCC during normal
operating.
The 2nd one is VVCC >25.5V and last for 120us and the
IC enters Auto Restart Mode. This 25.5V Vcc OVP
protection is inactivated during burst mode.
The Thermal Shutdown block monitors the junction
temperature of the IC. After detecting a junction
temperature higher than 130°C, the Auto Restart Mode
is entered.
In case the pre-defined auto-restart features are not
sufficient, there is a customer defined external Auto-
restart Enable feature. This function can be triggered
by pulling down the BA pin to < 0.33V. It can simply add
a trigger signal to the base of the externally added
transistor, TAE at the BA pin. When the function is
enabled, the gate drive switching will be stopped and
then the IC will enter auto-restart mode if the signal
persists. To ensure this auto-restart function will not be
mis-triggered during start up, a 1ms delay time is
implemented to blank the unstable signal.
VCC undervoltage is the Vcc voltage drop below Vcc
turn off threshold. Then the IC will turn off and the start
up cell will turn on automatically. And this leads to Auto
Restart Mode.
Short Optocoupler also leads to VCC undervoltage.
When the FB pin is pulled low, there is no switching
pulse. Then the Vcc will drop to Vcc turn off threshold.
And it leads to Auto Restart Mode.

Input Power Curve
Version 2.1 31 7 May 2011
7 Input Power Curve
Two input power curves giving the typical input power versus ambient temperature are showed below;
Vin=85Vac~265Vac (Figure 68) and Vin=230Vac+/-15% (Figure 69). The curves are derived based on a typical
discontinuous mode flyback model which considers either 50% maximum duty ratio or 100V maximum secondary
to primary reflected voltage (higher priority). The calculation is based on RthSA=2.7K/W as heatsink and
RthCS=1.1K/W as thermal grease thermal resistance. The input power already includes the power loss at input
common mode choke, bridge rectifier and the CoolMOS. The device saturation current (ID_Puls @ Tj=125°C) is also
considered.
To estimate the output power of the device, it is simply multiplying the input power at a particular operating ambient
temperature with the estimated efficiency for the application. For example, a wide range input voltage (Figure 68),
operating temperature is 50°C, estimated efficiency is 80%, then the estimated output power is 83W (104W *
80%).

Schematic for recommended PCB layout
Version 2.1 34 7 May 2011
10 Schematic for recommended PCB layout
Figure 72 Schematic for recommended PCB layout
General guideline for PCB layout design using F3/F3R CoolSET (refer to Figure 72):
1. “Star Ground “at bulk capacitor ground, C11:
“Star Ground “means all primary DC grounds should be connected to the ground of bulk capacitor C11
separately in one point. It can reduce the switching noise going into the sensitive pins of the CoolSET device
effectively. The primary DC grounds include the followings.
a. DC ground of the primary auxiliary winding in power transformer, TR1, and ground of C16 and Z11.
b. DC ground of the current sense resistor, R12
c. DC ground of the CoolSET device, GND pin of IC11; the signal grounds from C13, C14, C15 and collector of
IC12 should be connected to the GND pin of IC11 and then “star “connect to the bulk capacitor ground.
d. DC ground from bridge rectifier, BR1
e. DC ground from the bridging Y-capacitor, C4
2. High voltage traces clearance:
High voltage traces should keep enough spacing to the nearby traces. Otherwise, arcing would incur.
a. 400V traces (positive rail of bulk capacitor C11) to nearby trace: > 2.0mm
b. 600V traces (drain voltage of CoolSET IC11) to nearby trace: > 2.5mm
3. Filter capacitor close to the controller ground:
Filter capacitors, C13, C14 and C15 should be placed as close to the controller ground and the controller pin
as possible so as to reduce the switching noise coupled into the controller.
Guideline for PCB layout design when >3KV lightning surge test applied (refer to Figure 72):
1. Add spark gap
Spark gap is a pair of saw-tooth like copper plate facing each other which can discharge the accumulated
charge during surge test through the sharp point of the saw-tooth plate.
a. Spark Gap 3 and Spark Gap 4, input common mode choke, L1:
Gap separation is around 1.5mm (no safety concern)
CoolSET®-F3R
ICE3BR1465JF
Schematic for recommended PCB layout
Version 2.1 35 7 May 2011
b. Spark Gap 1 and Spark Gap 2, Live / Neutral to GROUND:
These 2 Spark Gaps can be used when the lightning surge requirement is >6KV.
230Vac input voltage application, the gap separation is around 5.5mm
115Vac input voltage application, the gap separation is around 3mm
2. Add Y-capacitor (C2 and C3) in the Live and Neutral to ground even though it is a 2-pin input
3. Add negative pulse clamping diode, D11 to the Current sense resistor, R12:
The negative pulse clamping diode can reduce the negative pulse going into the CS pin of the CoolSET and
reduce the abnormal behavior of the CoolSET. The diode can be a fast speed diode such as IN4148.
The principle behind is to drain the high surge voltage from Live/Neutral to Ground without passing through the
sensitive components such as the primary controller, IC11.
