Description
This device is an N-channel Power MOSFET. It
associates the latest low voltage STripFET™ in N-
channel version to a low drop Schottky diode.
Such configuration is extremely versatile in
implementing, a large variety of DC-DC
converters for printers, portable equipment, and
cellular phones.
