FDS6984AS
Dual Notebook Power Supply N-Channel PowerTrench
SyncFET
General Description
2005 Fairchild Semiconductor Corporation
FDS6984AS Rev A(X)
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 low-
side switch (Q2) is optimized to reduce conduction
losses. Q2 also includes a patented combination of a
MOSFET monolithically integrated with a Schottky
diode.
