Analog Power P-Channel 20-V (D-S) 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. • • • • Low rDS(on) provides higher efficiency and extends battery life Low thermal impedance copper leadframe SOT-23 saves board space Fast switching speed High performance trench technology AM2305P PRO DU C T SU MMA RY V ) rDS(on) (O H M) DS (V 0.043 @ V G S = -4.5V -20 0.054 @ V G S = -2.5V 0.120 @ V G S = -1.8V ID (A ) -4.5 -4.0 -2.7 G D S ABSOLUTE MAXIMUM RATINGS (TA = 25 oC UNLESS OTHERWISE NOTED) [ ... ]
