Description
These Power MOSFETs have been developed
using STMicroelectronics’ unique STripFET
process, which is specifically designed to
minimize input capacitance and gate charge.
This renders the devices 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.
