N-Channel Logic Level PowerTrenchTM MOSFET

FDS6630A

April 1999

General Description

This N-Channel Logic Level MOSFET is produced using
Fairchild Semiconductor's advanced PowerTrench process
that has been especially tailored to minimize on-state
resistance and yet maintain superior switching
performance.

These devices are well suited for low voltage and battery
powered applications where low in-line power loss and
fast switching are required.

Applications

• DC/DC converter

• Load switch

• Motor drives
