FDP2570/FDB2570

August 2001

General Description

This N-Channel MOSFET has been designed
specifically for switching on the primary side in the
isolated DC/DC converter application. Any applicat ion
requiring a 150V MOSFETs with low on-resistance and
fast switching will benefit.

These MOSFETs feature faster switching and lower
gate charge than other MOSFETs with comparable

specifications.

RDS

(ON)

The result is a MOSFET that is easy and safer to drive
(even at very high frequencies), and DC/DC power
supply designs with higher overall efficiency.
