Fairchild FDS6982AS Dual Notebook Power Supply N-Channel MOSFET Datasheet

The FDS6982AS is a device designed to replace two single SO-8 MOSFETs and a Schottky diode in synchronous DC:DC power supplies that provide various peripheral voltages for notebook computers and other battery-powered electronic devices. It 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.
