These miniature surface mount MOSFETs utilize a

high cell density trench process to provide low

rDS(on) and to ensure minimal power loss and heatdissipation. 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.
