Analog Power
N-Channel 20V (D-S) MOSFET
These miniature surface mount MOSFETs utilize a
high cell density trench process to provide low
r
DS(on)
and to ensure minimal power loss and heat
dissipation. Typical applications are DC-DC
converters and power management in portable and
battery-powered products such as computers,
printers, PCMCIA cards, cellular and cordless
telephones.
