FDS6984AS: 30V Dual Notebook Power Supply N-Channel PowerTrench® SyncFET™

The FDS6984AS 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. FDS6984AS 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 a patented combination of a MOSFET monolithically integrated with a Schottky diode.
