FDS6982AS
Dual Notebook Power Supply N-Channel PowerTrench® SyncFET
General Description
Features
tm
The FDS6982AS is designed to replace two single SO-
8 MOSFETs and Schottky diode in synchronous
DC:DC power supplies that provide various peripheral
voltages for notebook computers and other battery
powered electronic devices. FDS6982AS contains two
unique 30V, N-channel, logic level, PowerTrench
MOSFETs designed to maximize power conversion
efficiency. 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. Q2 also includes an integrated
Schottky diode using Fairchild’s monolithic SyncFET
technology.
