Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please

Description
The XS™ DrMOS family is Fairchild’s next-generation,
fully optimized, ultra-compact, integrated MOSFET plus
driver power stage solution for high-current, high-
frequency, synchronous buck DC-DC applications. The
FDMF6824B integrates a driver IC, two power
MOSFETs, and a bootstrap Schottky diode into a
thermally enhanced, ultra-compact 6x6mm package.
With an integrated approach, the complete switching
power stage is optimized with regard to driver and
MOSFET dynamic performance, system inductance,
and power MOSFET RDS(ON). XS™ DrMOS uses
Fairchild's high-performance PowerTrench® MOSFET
technology, which dramatically reduces switch ringing,
eliminating the need for snubber circuit in most buck
converter applications.
A driver IC with reduced dead times and propagation
delays further enhances the performance. A thermal
warning function warns of a potential over-temperature
situation. The FDMF6824B also incorporates a Skip
Mode (SMOD#) for improved light-load efficiency. The
FDMF6824B also provides a 3-state 5 V PWM input for
compatibility with a wide range of PWM controllers.

Note:
1. IO(AV) is rated using Fairchild’s DrMOS evaluation board, at TA = 25°C, with natural convection cooling. This rating
is limited by the peak DrMOS temperature, TJ = 150°C, and varies depending on operating conditions and PCB
layout. This rating can be changed with different application settings.
Recommended Operating Conditions
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to Absolute Maximum Ratings.

Note:
2. Operating at high VIN can create excessive AC overshoots on the VSWH-to-GND and BOOT-to-GND nodes
during MOSFET switching transients. For reliable DrMOS operation, VSWH-to-GND and BOOT-to-GND must
remain at or below the Absolute Maximum Ratings shown in the table above. Refer to the “Application
Information” and “PCB Layout Guidelines” sections of this datasheet for additional information.

FDMF6824B • Rev. 1.0.1 12
FDMF6824B — Extra-Small, High-Performance, High-Frequency DrMOS Module
Functional Description
The FDMF6824B is a driver-plus-FET module optimized
for the synchronous buck converter topology. A single
PWM input signal is all that is required to properly drive
the high-side and the low-side MOSFETs. Each part is
capable of driving speeds up to 1 MHz.
VCIN and Disable (DISB#)
The VCIN pin is monitored by an Under-Voltage Lockout
(UVLO) circuit. When VCIN rises above ~3.1 V, the driver
is enabled. When VCIN falls below ~2.7 V, the driver is
disabled (GH, GL=0). The driver can also be disabled by
pulling the DISB# pin LOW (DISB# < VIL_DISB), which
holds both GL and GH LOW regardless of the PWM
input state. The driver can be enabled by raising the
DISB# pin voltage HIGH (DISB# > VIH_DISB).

Note:
3. DISB# internal pull-down current source is 10 µA.
Thermal Warning Flag (THWN#)
The FDMF6824B provides a thermal warning flag
(THWN#) to warn of over-temperature conditions. The
thermal warning flag uses an open-drain output that
pulls to CGND when the activation temperature (150°C)
is reached. The THWN# output returns to a high-
impedance state once the temperature falls to the reset
temperature (135°C). For use, the THWN# output
requires a pull-up resistor, which can be connected to
VCIN. THWN# does NOT disable the DrMOS module.
Figure 26. THWN Operation
Three-State PWM Input
The FDMF6824B incorporates a three-state 5 V PWM
input gate drive design. The three-state gate drive has
both logic HIGH level and LOW level, along with a
three-state shutdown window. When the PWM input
signal enters and remains within the three-state window
for a defined hold-off time (tD_HOLD-OFF), both GL and GH
are pulled LOW. This enables the gate drive to shut
down both high-side and low-side MOSFETs to support
features such as phase shedding, which is common on
multi-phase voltage regulators.
Exiting Three-State Condition
When exiting a valid three-state condition, the
FDMF6824B follows the PWM input command. If the
PWM input goes from three-state to LOW, the low-side
MOSFET is turned on. If the PWM input goes from
three-state to HIGH, the high-side MOSFET is turned
on. This is illustrated in Figure 27. The FDMF6824B
design allows for short propagation delays when exiting
the three-state window (see Electrical Characteristics).
Low-Side Driver
The low-side driver (GL) is designed to drive a ground-
referenced, low-RDS(ON), N-channel MOSFET. The bias
for GL is internally connected between the VDRV and
CGND pins. When the driver is enabled, the driver's
output is 180° out of phase with the PWM input. When
the driver is disabled (DISB#=0 V), GL is held LOW.
High-Side Driver
The high-side driver (GH) is designed to drive a floating
N-channel MOSFET. The bias voltage for the high-side
driver is developed by a bootstrap supply circuit
consisting of the internal Schottky diode and external
bootstrap capacitor (CBOOT). During startup, VSWH is held
at PGND, allowing CBOOT to charge to VDRV through the
internal diode. When the PWM input goes HIGH, GH
begins to charge the gate of the high-side MOSFET (Q1).
During this transition, the charge is removed from CBOOT
and delivered to the gate of Q1. As Q1 turns on, VSWH
rises to VIN, forcing the BOOT pin to VIN + VBOOT, which
provides sufficient VGS enhancement for Q1. To complete
the switching cycle, Q1 is turned off by pulling GH to
VSWH. CBOOT is then recharged to VDRV when VSWH falls to
PGND. GH output is in-phase with the PWM input. The
high-side gate is held LOW when the driver is disabled or
the PWM signal is held within the three-state window for
longer than the three-state hold-off time, tD_HOLD-OFF.

Adaptive Gate Drive Circuit
The driver IC advanced design ensures minimum
MOSFET dead-time, while eliminating potential shoot-
through (cross-conduction) currents. It senses the state
of the MOSFETs and adjusts the gate drive adaptively
to ensure they do not conduct simultaneously. Figure 27
provides the relevant timing waveforms. To prevent
overlap during the LOW-to-HIGH switching transition
(Q2 off to Q1 on), the adaptive circuitry monitors the
voltage at the GL pin. When the PWM signal goes
HIGH, Q2 begins to turn off after a propagation delay
(tPD_PHGLL). Once the GL pin is discharged below 1.0 V,
Q1 begins to turn on after adaptive delay tD_DEADON.
To preclude overlap during the HIGH-to-LOW transition
(Q1 off to Q2 on), the adaptive circuitry monitors the
voltage at the GH-to-PHASE pin pair. When the PWM
signal goes LOW, Q1 begins to turn off after a
propagation delay (tPD_PLGHL). Once the voltage across
GH-to-PHASE falls below 2.2 V, Q2 begins to turn on
after adaptive delay tD_DEADOFF.

Skip Mode (SMOD#)
The Skip Mode function allows for higher converter
efficiency when operated in light-load conditions. When
SMOD# is pulled LOW, the low-side MOSFET gate
signal is disabled (held LOW), preventing discharge of
the output capacitors as the filter inductor current
attempts reverse current flow – known as “Diode
Emulation” Mode.
When the SMOD# pin is pulled HIGH, the synchronous
buck converter works in Synchronous Mode. This mode
allows for gating on the Low Side MOSFET. When the
SMOD# pin is pulled LOW, the low-side MOSFET is
gated off. If the SMOD# pin is connected to the PWM
controller, the controller can actively enable or disable
SMOD# when the controller detects light-load condition
from output current sensing. Normally this pin is active
LOW. See Figure 28 for timing delays.

FDMF6824B — Extra-Small, High-Performance, High-Frequency DrMOS Module
Application Information
Supply Capacitor Selection
For the supply inputs (VCIN), a local ceramic bypass
capacitor is recommended to reduce noise and to
supply the peak current. Use at least a 1 µF X7R or X5R
capacitor. Keep this capacitor close to the VCIN pin and
connect it to the GND plane with vias.
Bootstrap Circuit
The bootstrap circuit uses a charge storage capacitor
(CBOOT), as shown in Figure 30. A bootstrap capacitance
of 100 nF X7R or X5R capacitor is usually adequate. A
series bootstrap resistor may be needed for specific
applications to improve switching noise immunity. The
boot resistor may be required when operating above
15 VIN and is effective at controlling the high-side
MOSFET turn-on slew rate and VSHW overshoot. RBOOT
values from 0.5 to 3.0 Ω are typically effective in
reducing VSWH overshoot.
VCIN Filter
The VDRV pin provides power to the gate drive of the
high-side and low-side power MOSFET. In most cases,
it can be connected directly to VCIN, the pin that
provides power to the logic section of the driver. For
additional noise immunity, an RC filter can be inserted
between the VDRV and VCIN pins. Recommended
values would be 10 Ω and 1 µF.

FDMF6824B — Extra-Small, High-Performance, High-Frequency DrMOS Module
PCB Layout Guidelines
Figure 31 and Figure 32 provide an example of a proper
layout for the FDMF6824B and critical components. All
of the high-current paths, such as VIN, VSWH, VOUT,
and GND copper, should be short and wide for low
inductance and resistance. This aids in achieving a
more stable and evenly distributed current flow, along
with enhanced heat radiation and system performance.
Recommendations for PCB Designers
1. Input ceramic bypass capacitors must be placed
close to the VIN and PGND pins. This helps reduce
the high-current power loop inductance and the input
current ripple induced by the power MOSFET
switching operation.
2. The VSWH copper trace serves two purposes. In
addition to being the high-frequency current path
from the DrMOS package to the output inductor, it
serves as a heat sink for the low-side MOSFET in
the DrMOS package. The trace should be short and
wide enough to present a low-impedance path for
the high-frequency, high-current flow between the
DrMOS and inductor. The short and wide trace
minimizes electrical losses as well as the DrMOS
temperature rise. Note that the VSWH node is a high-
voltage and high-frequency switching node with high
noise potential. Care should be taken to minimize
coupling to adjacent traces. Since this copper trace
acts as a heat sink for the lower MOSFET, balance
using the largest area possible to improve DrMOS
cooling while maintaining acceptable noise emission.
3. An output inductor should be located close to the
FDMF6824B to minimize the power loss due to the
VSWH copper trace. Care should also be taken so the
inductor dissipation does not heat the DrMOS.
4. PowerTrench® MOSFETs are used in the output
stage and are effective at minimizing ringing due to
fast switching. In most cases, no VSWH snubber is
required. If a snubber is used, it should be placed
close to the VSWH and PGND pins. The selected
resistor and capacitor need to be the proper size for
power dissipation.
5. VCIN, VDRV, and BOOT capacitors should be
placed as close as possible to the VCIN-to-CGND,
VDRV-to-CGND, and BOOT-to-PHASE pin pairs to
ensure clean and stable power. Routing width and
length should be considered as well.
6. Include a trace from the PHASE pin to the VSWH pin
to improve noise margin. Keep this trace as short as
possible.
7. The layout should include the option to insert a
small-value series boot resistor between the boot
capacitor and BOOT pin. The boot-loop size,
including RBOOT and CBOOT, should be as small as
possible. The boot resistor may be required when
operating above 15 VIN and is effective at controlling
the high-side MOSFET turn-on slew rate and VSHW
overshoot. RBOOT can improve noise operating
margin in synchronous buck designs that may have
noise issues due to ground bounce or high positive
and negative VSWH ringing. Inserting a boot
resistance lowers the DrMOS efficiency. Efficiency
versus noise trade-offs must be considered. RBOOT
values from 0.5 to 3.0 are typically effective in
reducing VSWH overshoot.
8. The VIN and PGND pins handle large current
transients with frequency components greater than
100 MHz. If possible, these pins should be
connected directly to the VIN and board GND
planes. The use of thermal relief traces in series with
these pins is discouraged since this adds inductance
to the power path. This added inductance in series
with either the VIN or PGND pin degrades system
noise immunity by increasing positive and negative
VSWH ringing.
9. GND pad and PGND pins should be connected to
the GND copper plane with multiple vias for stable
grounding. Poor grounding can create a noise
transient offset voltage level between CGND and
PGND. This could lead to faulty operation of the gate
driver and MOSFETs.
10. Ringing at the BOOT pin is most effectively
controlled by close placement of the boot capacitor.
Do not add an additional BOOT to the PGND
capacitor. This may lead to excess current flow
through the BOOT diode.
11. The SMOD# and DISB# pins have weak internal
pull-up and pull-down current sources, respectively.
These pins should not have any noise filter
capacitors. Do not to float these pins unless
absolutely necessary.
12. Use multiple vias on the VIN and VOUT copper
areas to interconnect top, inner, and bottom layers
to distribute current flow and heat conduction. Do
not put many vias on the VSWH copper to avoid
extra parasitic inductance and noise on the
switching waveform. As long as efficiency and
thermal performance are acceptable, place only
one VSWH copper on the top layer and use no vias
on the VSWH copper to minimize switch node
parasitic noise. Vias should be relatively large and
of reasonably low inductance. Critical high-
frequency components, such as RBOOT, CBOOT, RC
snubber, and bypass capacitors; should be located
as close to the respective DrMOS module pins as
possible on the top layer of the PCB. If this is not
feasible, they can be connected from the backside
through a network of low-inductance vias.
