CHARACTERIZATION
DESCRIPTION
This Power MOSFET series realized with STMicroelectronics uniqueSTripFET 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 for Telecom and Computer application. It
is also intended for any application with low gate
charge drive requirements
APPLICATIONS
■ HIGH-EFFICIENCY DC-DC CONVERTERS
■ UPS AND MOTOR CONTRO L
