The FDS6982S 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. FDS6982S contains two unique 30V, N-channel, logic level, PowerTrench MOSFETs designed to maximize power conversion efficiency.

The FDS6982S 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.
