AM6968N - Analog Power

Analog Power
AM6968N
Dual N-Channel Logical Level MOSFET
These miniature surface mount MOSFETs utilize
High Cell Density process. Low rDS(on) assures
minimal power loss and conserves energy, making
this device ideal for use in power management
circuitry. Typical applications are DC-DC
converters, power management in portable and
battery-powered products such as computers,
printers, PCMCIA cards, cellular and cordless
telephones.
