Description

This Power MOSFET has been developed using

STMicroelectronics’ unique STripFET™ process,

which is specifically designed to minimize input

capacitance and gate charge. This renders the

device suitable for use as primary switch in

advanced high-efficiency isolated DC-DC

converters for telecom and computer applications,

and applications with low gate charge driving

requirements.
