AP3783R
PRIMARY SIDE REGULATED SWITCHING MODE POWER SUPPLY CONTROLLER
Description
The AP3783R is a high frequency, high efficiency and high accuracy
switching mode power supply controller to drive power MOSFET for
5V/2A battery charger/adapter applications. The controller regulates
the output voltage and current in the primary side by piece-wise Pulse
Frequency Modulation (p-PFM) in discontinuous conduction mode
(DCM). The system operating frequency reduces linearly from heavy
load to light load in each interval of the p-PFM, and enters constant
current mode when the load current equals to the maximum system
output current.
The AP3783R provides accurate constant voltage (CV), constant
current (CC) and outstanding dynamic performance without requiring
an opto-coupler. It also eliminates the need of loop compensation
circuitry while maintaining stability.
The AP3783R provides valley turn-on function and 3-Segment drive
current to improve the power supply EMI performance. The AP3783R
also has built-in fixed cable voltage drop compensation (8%, 4% and
2% of nominal system output voltage to meet various cables with
different length and gauge) and adjustable line voltage compensation.
The AP3783R achieves excellent regulation and high average
efficiency, less than 2s startup time for 30mW standby power solution.
When AP3783R is used with APR3415, good undershoot and
efficiency performances can be achieved.
The AP3783R is packaged in SOT26.

AP3783R
Operation Principle Description (Cont.)
Figure 2 shows the typical waveforms which demonstrate the basic operating principle of AP3783R application. And the parameters are defined as
following.
IP---The primary side current
IS ---The secondary side current
IPK---Peak value of primary side current
IPKS---Peak value of secondary side current
VSEC---The transient voltage at secondary winding
VO---The output voltage
VAUX---The transient voltage at auxiliary winding
VA--- The stable voltage at auxiliary winding when rectification diode is in conducting status, which equals the sum of voltage VCC and the forward
voltage drop of auxiliary diode
tSW ---The period of switching frequency
tONP ---The conduction time when primary side switch is “ON”
tONS ---The conduction time when secondary side diode is “ON”
tOFF ---The dead time when neither primary side switch nor secondary side diode is “ON”
tOFFS --- The time when secondary side diode is “OFF”
For primary-side regulation, the primary current ip(t) is sensed by a current sense resistor RCS (as shown in Figure 1).The current rises up linearly
at a rate of:
M

dttdip )(V
)( IN
(1)
As illustrated in Figure 2, when the current ip(t) rises up to IPK, the switch Q1 turns off. The constant peak current is given by:

The energy stored in the magnetizing inductance LM each cycle is therefore:

So the power transferring from the input to the output is given by:

(4)
Where, the fSW is the switching frequency. When the peak current IPK is constant, the output power depends on the switching frequency fSW.
Constant Voltage Operation
As to constant-voltage (CV) operation mode, the AP3783R detects the auxiliary winding voltage at FB pin to regulate the output voltage. The
auxiliary winding voltage is coupled with secondary side winding voltage, so the auxiliary winding voltage at tONS is:
VdVo

Where Vd is the conduction voltage drop of MOSFET in APR3415.

Figure 3. Auxiliary Voltage Waveform
The voltage detection point is at a constant delay time of tONS. The constant delay time is changed with the different primary peak current. The
CV loop control function of AP3783R then generates a tOFF to regulate the output voltage.
Constant Current Operation
The AP3783R can work in constant-current (CC) mode. Figure 2 shows the secondary current waveforms.
In CC operation mode, the CC control loop of AP3783R will keep a fixed proportion between tONS and tOFFS. The fixed proportion is

Therefore, AP3783R can realize CC mode operation by constant primary peak current and fixed diode conduction duty cycle.
Multiple Segment Constant Peak Current
As to the original PFM PSR system, the switching frequency decreases with output current decreasing, which will encounter audible noise issue
since switching frequency decreases to audio frequency range, about less than 20kHz.
In order to avoid audible noise issue, AP3783R uses 2-segment constant primary peak current control method. At constant voltage mode, the
current sense threshold voltage is of multiple segments with different loading, as shown in Figure 4, which are VCS_H for high load, VCS_L for
light load and LL Mode. At constant current mode, the current sense threshold voltage is always VCS_H.

Figure 4. Multiple Segment Peak Current at CV Mode
It can be seen from Figure 4, with multiple segment peak current control, AP3783R power system can keep switching frequency above 24kHz
at whole heavy load and most of light load to guarantee the audible noise free performance.
Constant Voltage Operation in LL Mode and Dynamic Response
In primary side regulation of AP3783R application, APR3415 must be used at secondary side as the output voltage regulator, low standby power
and excellent dynamic response can be achieved. When the output voltage detected by APR3415 is lower than its trigger voltage, APR3415
outputs periodical signals which will be coupled to auxiliary side. When AP3783R detects the signal which is valid that the signal voltage is higher
than VTRIGGER and tOFF is longer than tDELAY, AP3783R will begin an operating pulse, then primary switch immediately turns on to provide one energy
pulse to output terminal and primary VCC.
By fast response and cooperation, APR3415 and AP3783R can maintain a constant output voltage with very low operating frequency in LL mode
and also can effectively improve dynamic performance for primary side regulation power system.
The conditions of entering LL mode---VCPC<20mV and tOFF>256μs.
The condition of exiting LL mode---VCPC ≥40mV or tOFF<256μs.
The critical point of the LL mode is generally about 5% IO(MAX).
3-Segment Drive Current for Radiative EMI Suppression
When the power switch is turned on, a turn-on spike will occur, that worsens the radiative EMI. It is an effective way to decrease drive current
before gate voltage gets to miller platform. The AP3783R uses 3-segment drive current for radiative EMI suppression, as shown in Figure 5.
When gate voltage gets to 6V, the AP3783R drive current switches from low current (43mA) to high current (110mA). When the gate voltage
gets to 10V, the drive current will decrease gradually to 0mA until the gate voltage goes up to the clamp voltage (11V).

Leading Edge Blanking (LEB) Time
When the power switch is turned on, a turn-on spike will occur on the sense-resistor. To avoid false turn off switch, a leading-edge blanking is
built in. During this blanking time, the current sense comparator is disabled and the external power switch cannot be turned off.
Adjustable Line Compensation and Fixed Cable Compensation
The AP3783R power system can adjust line compensation by changing the upper resistor at FB pin. The line compensation capability is
increased by decreasing the resistance of the upper FB resistor.
Cable compensation is fixed in AP3783R.
Valley Turn-on
When the off time (tOFF) is lower than 16ms, AP3783R power system can work with valley turn-on. It can reduce MOSFET switching on power
losses which is resulted from the equivalent output capacitance. At the same time, because of valley turn-on the switching frequency has the
random jitter feature, which will be benefit for conductive EMI performance. And valley turn-on can also reduce the power switch turn on spike
current and then result in the better radiative EMI performance.
Frequency Jitter
Even though the valley turn-on function can lead the random frequency jitter feature, an active frequency jitter function is added to AP3783R to
ensure the frequency jitter performance in the whole loading condition. By adjusting the VCS_REF with deviation of 5.0% every 256μs cycle, the
active frequency jitter can be realized.
Short Circuit Protection (SCP)
Short Circuit Protection (SCP) detection principle is similar to the normal output voltage feedback detection by sensing FB pin voltage. When
the detected FB pin voltage is below VFB(SCP) for a duration of about 128ms, the SCP is triggered. Then the AP3783R enters hiccup mode that
the IC immediately shuts down and then restarts, so that the VCC voltage changes between VTH_ST and UVLO threshold until VFB(SCP) condition
is removed.
As to the normal system startup, the time duration of FB pin voltage below VFB(SCP) should be less than tSCP to avoid entering SCP mode. But
for the output short condition or the output voltage below a certain level, the SCP mode will be triggered.

Figure 6 is the AP3783R normal start-up waveform that the voltage of FB pin is above VFB(SCP) during tSCP after VCC gets to the VTH_ST, which
doesn’t enter the SCP mode. As shown in Figure 7, VOUT is short and the voltage of FB pin is lower than VFB(SCP) during tSCP, the AP3783R
triggers the SCP and enter the hiccup mode.

OVP
The AP3783R includes output over-voltage protection (OVP). If the voltage at FB pin exceeds VFB(OVP), the AP3783R immediately shuts down
and keeps the internal circuitry enabled to discharge the VCC capacitor to the UVLO turn-off threshold. After that, the device returns to the start
state and a start-up sequence ensues.
OTP
If the junction temperature reaches the threshold of +140⁰C, AP3783R shuts down immediately. Before VCC voltage decreases to UVLO, if the
junction temperature decreases to +100⁰C, AP3783R can recover to normal operation. If not, the power system enters restart Hiccup mode until
the junction temperature decreases below +100⁰C.
