Description
$4!"
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 DCDC converters for telecom and computer
applications, and applications with low gate
charge driving requirements.
