PRELIMINARY

Publication Order Number:

DS-AM4844NE_A

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.
