FDS6982
Dual N-Channel, Notebook Power Supply MOSFET
General 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, 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 for low conduction losses (less than 20m at VGS 4.5V).

Features
Q2: 8.6A, 30V. RDS(on) 0.015 VGS 10V RDS(on) 0.020 VGS 4.5V Q1: 6.3A, 30V. RDS(on) 0.028 VGS 10V RDS(on) 0.035 VGS 4.5V

Fast switching speed. High performance trench technology for extremely low RDS(ON).

Applications Battery powered synchronous DC:DC converters. Embedded DC:DC conversion.
