AM3438NE
Analog Power
N-Channel Logic Level MOSFET
These miniature surface mount MOSFETs
utilize a high cell density trench process to
provide low rDS(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.
