FDQ7238S
Dual Notebook Power Supply N-Channel PowerTrench in SO-14 Package
General Description
The FDQ7238S 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’s SyncFET TM technology.
