1 / 3 page 1 AM4481P Analog Power PRELIMINARY Publication Order Number: DS-AM4481_B 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. VDS (V) rDS(on) m(Ω)ID (A) 126 @VGS=-10V 6.8 146 @VGS=-4.5V 5.9 PRODUCTSUMMARY -80 P-Channel 80-V (D-S) MOSFET •Low r DS(on) provides higher efficiency and extends battery life • Low thermal impedance copper leadframe SOIC-8 saves board space • Fast switching speed • High performance trench technology Notes a.
