Analog Power
Dual N-Channel Logic Level 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.
