1 / 3 page AM4934N Analog Power PRELIMINARY Publication Order Number: DS-AM4934_A 1 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. Dual N-Channel 30-V (D-S) MOSFET • Low rDS(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.
