FDQ7698S
Dual Notebook Power Supply N-Channel PowerTrench in SO-14 Package
General Description
The FDQ7698S 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
Fairchild鈥檚 SyncFET
TM
technology.
