FDS6982AS

FET, MOSFET Arrays Overview

The onsemi FDS6982AS is a dual N-channel PowerTrench SyncFET designed for synchronous DC-DC power supplies in notebook computers and battery-powered devices. It integrates two unique logic-level MOSFETs to maximize power conversion efficiency. The primary switch (Q2) offers an RDS(on) of 0.015 Ω at VGS=10V, while the secondary (Q1) provides 0.028 Ω at VGS=10V. Both channels feature low gate charge and fast switching speeds. The component utilizes high-performance trench technology for extremely low on-resistance and is housed in an 8-SOIC surface-mount package.
