AM4434N AO4456/MC4456 Analog Power Freescale N-Channel 30-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. • • • • PRODUCT SUMMARY VDS (V) rDS (on ) m(Ω) 6 @ VGS = 4.5V 30 8 @ VGS = 2.5V 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 ID (A) 18.6 16.1 1 8 2 7 3 6 4 5 o AB SOLUTE MAXIMUM RATINGS (TA = 25 C UNLESS OTHERWISE NOTED) Parame te r Symbol Maximum Units Drain-Source Voltage VDS 30 V Gate-Source Voltage VGS 12 o Continuous Drain Current TA=25 C a o 18.6 ID b Pulsed Drain Current Continuous Source Current (Diode Conduction) a IDM 60 IS 2.9 o TA=25 C a Power Dissipation o THERMAL RESISTANCE RATINGS Parameter Maximum Junction-to-Ambient a Steady State W 2.2 TJ, Tstg Symbol t <= 10 sec A 3.1 PD TA=70 C Operating Junction and Storage Temperature Range A 15.7 TA=70 C R θJA o -55 to 150 Maximum 40 80 Units o C/W C/W o Notes a.
