Description
This Power MOSFET series realized with
STMicroelectronics unique STripFET process has
specifically been designed to improve immunity to
space effect. It is therefore suitable as power
switch in mainly high-efficiency DC-DC converters
and Motor Control applications. It is also intended
for any application with low gate charge drive
requirements.
