Vishay Siliconix power MOSFETs combine optimized
performance specifications with miniaturized packaging to
meet the demands of dc-to-dc conversion circuitry in desktop
and notebook computers, PDAs, servers, routers, networks,
and automobiles. For example, as CPU speeds and power
demands rise, our combination of advanced TrenchFET
®
and
PWM-optimized process technologies with innovative new
packages provide:
lowest on-resistance for minimum power dissipation
lowest gate charge for minimum switching losses
dV/dt shoot-thru immunity (
see page 10
dV/dt shoot-thru immunity (see page 10dV/dt shoot-thru immunity (
)
improved thermal management with higher
current capability
The result is high efficiency solutions, one such example is
illustrated in the Synchronous Buck DC-to-DC Converter
Efficiency Diagram shown to the right. These and other
power conversion applications benefit from the improvements
realized from combining our breakthrough technologies with
our DC-to-DC focus and experience.
Breakthroughs in thermal management for increasing power
density are achieved with packaging such as the PowerPAK
®
(Si7000 Series), the thermally enhanced D
2
PAK (SUM Series),
and ChipFET
®
(Si5000 Series). The PowerPAK SO-8 offers
the thermal resistance of a DPAK in an SO-8 footprint. The
PowerPAK 1212-8 is about half the size of a TSSOP-8 while
decreasing the thermal resistance by an order of magnitude.
The SUM Series reduces thermal resistance by 33% over
standard D
2
PAK packaging. ChipFET is 40% smaller than a
TSOP-6 package while offering lower on-resistance and lower
thermal resistance. Lower thermal resistance results in higher
possible maximum current and power dissipation.
Packaging ranges from the D
2
PAK (SUM or SUB Series), DPAK
(SUD Series) and PowerPAK (Si7000 Series) to the LITTLE
FOOT packages, which range from SO-8 (Si4000 Series)
down to the tiniest MOSFET available—in SC-89 (Si1000
Series) packaging.
See Appendix A on page 25 for more on
packaging
.
To save on valuable board space, LITTLE FOOT
®
Plus
integrates a Schottky diode, additional MOSFET and/or logic
into the same package as the Vishay Siliconix power MOSFET.
See pages 12, 14, 15 and 23 for more information
.
Besides saving on board space, Application-specific MOSFETs
(ASMs) also save on critical board space while providing
higher frequency performance by integrating functions such
as drivers in the same package as the power MOSFET.

pages 6 and 7 for more information.

Visit http://www.vishay.com/mosfets/wfet
for the most updated list of devices
New trench gate structure cuts C
rss
by two-
thirds and Q
gd
by half with minimal impact on
on-resistance performance
Efficiency goes up by more than 2.5% in a
typical high-side application, allowing either
cooler operation or operation at a higher output
current with the same efficiency
For high-side operation in notebook CPU
core dc-to-dc converters in single and multi-
phase configurations with a 20- to 40-A output
current at frequencies starting at 300 kHz
Lower on-resistance
means that more power
can be converted in
less space, and lower
gate-drain capacitance
means more efficient
switching at high
frequencies. Vishay’s new
WFET Power MOSFET
technology combines
both capabilities in a
single device. Combining
greatly reduced switching
losses with on-resistance,
WFET Power MOSFETs
offer an r
DS(on)
x Q
gd
figure of merit that is 60% lower than
previous-generation MOSFETs, an achievement that translates
directly into better efficiency for synchronous buck converters.
The first WFET products are designed for the dc-to-dc high
side in notebook CPU core converters in single and multi-
phase configurations with a 20-A (Si4390DY and Si7390DP) to
40-A (Si4392DY and Si7392DP) output current. The Si4390DY
and Si4392DY are offered in the LITTLE FOOT SO-8, and, for
improved thermal performance, the Si7390DP and Si7392DP
are offered in the PowerPAK SO-8.
For more details, see
pages 8-10
. Future WFET power MOSFETs will include devices
aimed at desktop computer and primary dc-to-dc converter
applications with breakdown voltages ranging from 8 V to 250 V.

TrenchFET Gen II products are the 30-V n-channel Si4320DY
(LITTLE FOOT SO-8) and Si7356DP (PowerPAK SO-8), both of
which are designed to serve as high-performing, cost-effective
solutions for low-side operation in synchronous buck dc-to-

Power MOSFET DC/DC Selector Guide
Synchronous Buck
The high-side device has a very short duty cycle because the
input voltage is much greater than the output voltage (V
in
= 12 V
or 20 V and V
out
= 1.6 V or lower).
1.
The main component of losses are “switching losses.”
In order to reduce them, a MOSFET is required to have:
I). Small R
g
and L
g
(gate inductance) to reduce
switching time constant
II). Small C
iss
for short current transients
III). Small C
gd
for short voltage transients
2.
Continuing with the lower capacitance values leads to
the second issue of reducing gate charge losses. This
can be done by selecting a device with small C
iss
and
C
gs
, that effectively requires a device with a small gate
charge.
3.
The final concern is conduction losses. This requires a
device with low on-resistance.
Although the first two points are related by gate charge and
selecting a device with a very low Q
g
is necessary, the trade
off is that a low Q
g
MOSFET will typically result in higher on-
resistance. Therefore, the figure of merit typically used for
device selection is the product of on-resistance and gate
charge, r
DS (on)
*
Q
g
. Different vendors have different processes,
yet for each process the r
DS (on)
*
Q
g
figure of merit is basically
a constant. A head-to-head comparision will show that
Vishay’s Siliconix Power MOSFET process has significantly
lower r
DS(on)
*
Q
g
than competitive processes.
High-Side MOSFET Selector (Q1)
PWM
Controller
Optimized MOSFET parameters for synchronous-buck
configuration, including theoretical and SPICE simulations and
extensive verification via bench testing, is summarized in these
design guidelines.
High-side and low-side MOSFET on-resistance ratios
for desktop and notebook core voltage are different
and can be summarized as follows:

A single device may not always be used due to current
requirements, however this ratio also reflects the effective
on-resistance of paralleled devices. Example: In a notebook
application, if the high side on-resistance is 21 mΩ, then the
low side on-resistance would be 7 mΩ. Analysis of gate drive
voltage versus MOSFET threshold voltage shows that for
notebook applications with a 5-V gate drive, a low threshold
voltage device is preferred for frequencies below 500 kHz for
the low-side MOSFET. Otherwise, a high threshold device
is used for the high-side and high frequency applications.
Threshold voltages can be found with more detailed device
parameters in

1.
Since the duty cycle is very long for the low-side,
the conduction losses are the main concern. Here,
selecting a MOSFET with a low on-resistance is
important.
2.
When the low-side turns off and the high-side MOSFET
turns on, there is a high dV/dt occurring at the output
node between the two MOSFETs. The dV/dt can inflect
a voltage on the gate of the low-side MOSFET due to
the Miller capacitance of the MOSFET structure. If the
gate voltage rises sufficiently high enough, the low-side
MOSFET can turn back on for a short period of time.
This condition has been labeled as “shoot-through”.
A lowside MOSFET requires a form of shoot-through
ruggedness. The key factor is the C

ratio. The ratio required depends on the MOSFET’s
C
iss
and the threshold voltage, V
th
. The table below
shows a basic guide line requirement of the ratio versus
the MOSFET threshold. As expected, the higher the
threshold voltage, the higher the Q
gd
/Q
gs
ratio can be.
3.
Since the current is already flowing through the output
inductor when the high-side is switching, it is important
that the switching losses are minimized. Current
capability of the MOSFET driver is limited when using
only the PWM controller. Thus, as with the high-side
device, select a device with small C
iss
and C
gs
. This
effectively requires a device with a small r
DS(on)
* Q
g
product.
4.
The final key factor of losses in the low-side is
switching frequency. As the frequency is increased,
reduction of R
g
, C
iss
, and C
gd
is important.

figure of merit is the key parameter to
MOSFET selection has it merits. However, shoot-through immunity and threshold voltage also play
as important factors to MOSFET selection.
The following table contains examples of best selection considering the different MOSFET
parameters as described above with the LITTLE FOOT and PowerPAK family. This chart is for
<25% high-side duty cycle applications.

P-Channel MOSFET Selector (Q1) - Synchronous Buck & Voltage Inverter
The losses associated with the high side device result
from both r
DS(on)
and switching time (Q
g
). Therefore, a good
compromise between r
DS(on)
and Q
g
is required for Q1.
