Description

This part is designed to replace two single SO-8  MOSFETs in synchronous DC:DC power supplies that provide the various peripheral voltage rails required in notebook computers and other battery powered electronic devices. FDS6982 contains two unique 30V, N-channel, logic level, PowerTrenchTM MOSFETs designed to maximize power conversion efficiency.

The FDS6982 high-side switch (Q1) is designed with specific emphasis on reducing switching losses while the low-side switch (Q2) is optimized for low conduction (less than 20mΩ at V_{GS = 4.5V).}
