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.
