Description Figure 1. Internal schematic diagram
This Power MOSFET series realized with
STMicroelectronics unique STripFET process has
specifically been designed to minimize input
capacitance and gate charge. It is therefore
suitable as primary switch in advanced high-
efficiency isolated DC-DC converters.
