FDS6984AS

Dual Notebook Power Supply N-Channel PowerTrench^®SyncFET^™

General Description

Features

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.

•

Q2:

Optimized to minimize conduction losses

Includes SyncFET Schottky diode

8.5A, 30V R_DS(on)max= 20 mΩ @ V_GS= 10V

R_DS(on)max= 28 mΩ @ V_GS= 4.5V

•

Q1:

Optimized for low switching losses

Low gate charge (8nC typical)

5.5A, 30V

R_DS(on)max= 31 mΩ @ V_GS= 10V

R_DS(on)max= 40 mΩ @ V_GS= 4.5V

The 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 a patented combination of a

MOSFET monolithically integrated with

diode.
