CHARACTERIZATION
DESCRIPTION
This 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 highefficiency, high-frequency isolate d DC-DC c onverters for
Telecom and Computer a pplications. It is also intended
for any applications with low gate drive requirements.
APPLICATIONS
■ HIGH-EFFICIENCY DC-DC CONVERTERS
■ UPS AND MOTOR CONTROL
