POWERTRENCH), Power
Stage, Asymetric Dual
General Description
This device includes two specialized N−Channel MOSFETs in a
dual PQFN package. The switch node has been internally connected to
enable easy placement and routing of synchronous buck converters.
The control MOSFET (Q1) and synchronous SyncFET™ (Q2) have
been designed to provide optimal power efficiency.

Pulse Test: Pulse Width < 300 ms, Duty cycle < 2.0%.
As an N−ch device, the negative Vgs rating is for low duty cycle pulse ocurrence only. No continuous rating is implied.
EAS of 40 mJ is based on starting TJ = 25°C; N−ch: L = 1 mH, IAS = 9 A, VDD = 27 V, VGS = 10 V. 100% test at L = 0.3 mH, IAS = 14 A.
EAS of 60 mJ is based on starting TJ = 25°C; N−ch: L = 1 mH, IAS = 11 A, VDD = 27 V, VGS = 10 V. 100% test at L = 0.3 mH, IAS = 18 A.

SyncFET Schottky Body Diode Characteristics
ON Semiconductor’s SyncFET process embeds a
Schottky diode in parallel with PowerTrench MOSFET.
This diode exhibits similar characteristics to a discrete
external Schottky diode in parallel with a MOSFET.
Figure 27 shows the reverse recovery characteristic of the
FDMS3604S.
Schottky barrier diodes exhibit significant leakage at high
temperature and high reverse voltage. This will increase the
power in the device.

APPLICATION INFORMATION
Switch Node Ringing Suppression
ON Semiconductor’s Power Stage products incorporate a
proprietary design* that minimizes the peak overshoot,
ringing voltage on the switch node (PHASE) without the
need of any external snubbing components in a buck
converter. As shown in the Figure 29, the Power Stage
solution rings significantly less than competitor solutions
under the same set of test conditions.

Recommended PCB Layout Guidelines
As a PCB designer, it is necessary to address critical issues
in layout to minimize losses and optimize the performance
of the power train. Power Stage is a high power density
solution and all high current flow paths, such as VIN (D1),
PHASE (S1/D2) and GND (S2), should be short and wide
for better and stable current flow, heat radiation and system
performance. A recommended layout procedure is
discussed below to maximize the electrical and thermal
performance of the part.
Figure 31. Recommended PCB Layout
Following is a guideline, not a requirement which the PCB designer should consider:
3. Output inductor location should be as close as
1. Input ceramic bypass capacitors C1 and C2 must
possible to the Power Stage device for lower
be placed close to the D1 and S2 pins of Power
power loss due to copper trace resistance. A

shorter and wider PHASE trace to the inductor
Frequency conduction loss induced by switching
reduces the conduction loss. Preferably the Power
operation. C1 and C2 show the bypass capacitors
Stage should be directly in line (as shown in
placed close to the part between D1 and S2. Input
Figure 32) with the inductor for space savings and
capacitors should be connected in parallel close to
compactness
the part. Multiple input caps can be connected
4. The POWERTRENCH Technology MOSFETs
depending upon the application
used in the Power Stage are effective at
2. The PHASE copper trace serves two purposes; In
minimizing phase node ringing. It allows the part

to operate well within the breakdown voltage
Stage package to the output inductor (L), it also
limits. This eliminates the need to have an external

snubber circuit in most cases. If the designer
Stage package. The trace should be short and wide
chooses to use an RC snubber, it should be placed
enough to present a low resistance path for the

high current flow between the Power Stage and the
pins to dampen the high−frequency ringing
inductor. This is done to minimize conduction
5. The driver IC should be placed close to the Power
losses and limit temperature rise. Please note that
Stage part with the shortest possible paths for the
the PHASE node is a high voltage and high
High Side gate and Low Side gates through a wide
frequency switching node with high noise
trace connection. This eliminates the effect of
potential. Care should be taken to minimize
parasitic inductance and resistance between the
coupling to adjacent traces. The reference layout

7. Use multiple vias on each copper area to
interconnect top, inner and bottom layers to help
smooth current flow and heat conduction. Vias
should be relatively large, around 8 mils to 10
mils, and of reasonable inductance. Critical high
frequency components such as ceramic bypass
caps should be located close to the part and on the
same side of the PCB. If not feasible, they should
be connected from the backside via a network of
low inductance vias
higher−frequency operation this impedance can
limit the gate current trying to charge the
MOSFET input capacitance. This will result in
slower rise and fall times and additional switching
losses. Power Stage has both the gate pins on the
same side of the package which allows for back
mounting of the driver IC to the board. This
provides a very compact path for the drive signals
and improves efficiency of the part
6. S2 pins should be connected to the GND plane
with multiple vias for a low impedance grounding.
Poor grounding can create a noise transient offset
voltage level between S2 and driver ground. This
could lead to faulty operation of the gate driver
