FDS6900AS Dual N-Ch PowerTrench® SyncFET™

Dual N-Ch PowerTrench® SyncFET™

General Description
The FDS6900AS 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. FDS6900AS 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 lowside
switch (Q2) is optimized to reduce conduction
losses. Q2 also includes an integrated Schottky diode
using Fairchild’s monolithic SyncFET technology.
