STS2DPFS20V
P-CHANNEL 20V - 0.14 Ω - 2.5A SO-8
2.7V-DRIVE STripFET™ II MOSFET PLUS SCHOTTKY DIODE
DESCRIPTION
This product associates the latest low voltage
StripFETœ in p-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.
