FDQ7238AS
Dual Notebook Power Supply N-Channel PowerTrench
廬
in SO-14 Package
General Description
The FDQ7238AS is designed to replace two single SO-
8 MOSFETs in DC to DC power supplies. The high-side
switch (Q1) is designed with specific emphasis on
reducing switching losses while the low-side switch
(Q2) is optimized to reduce conduction losses using
TM
technology. The FDQ7238AS
Fairchild鈥檚 SyncFET
includes a patented combination of a MOSFET
monolithically integrated with a Schottky diode.
