FDS6570A
Single N-Channel 2.5V Specified PowerTrench
MOSFET
FDS6570A
March 2000
General Description
This N-Channel 2.5V specified 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
• Battery protection
