Channel PowerTrench

SyncFET

General Description
Features
This MOSFET is designed to replace a single MOSFET
and parallel Schottky diode in synchronous DC:DC
power supplies.
This 30V MOSFET is designed to
maximize power conversion efficiency, providing a low
R
DS(ON)
and low gate charge.
The FDP6670S includes
an integrated Schottky diode using Fairchild’s
monolithic SyncFET technology.
The performance of
the FDP6670S/FDB6670S as the low-side switch in a
synchronous rectifier is indistinguishable from the
performance of the FDP6670A/FDB6670A in parallel
with a Schottky diode.

SyncFET Schottky Body Diode
Characteristics
Fairchild’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 12
FDP6670S.
Schottky barrier diodes exhibit significant leakage at
high temperature and high reverse voltage.
This will
increase the power in the device.
