Analog Power AM4922N N-Channel 20-V (D-S) MOSFET PRODUCT SUMMARY VDS (V) rDS(on) m(Ω) 22 @ VGS = 4.5V 20 28 @ VGS = 2.5V These miniature surface mount MOSFETs utilize High Cell Density process. Low rDS(on) assures minimal power loss and conserves energy, making this device ideal for use in power management circuitry. Typical applications are PWMDC-DC converters, power management in portable and battery-powered products such as computers, printers, battery charger, telecommunication power system, and telephones power system. • • • • Low rDS(on) Provides Higher Efficiency and Extends Battery Life Miniature SO-8 Surface Mount Package Saves Board Space High power and current handling capability Low side high current DC-DC Converter applications ID (A) 7.8 7.0 1 8 2 7 3 6 4 5 o ABSOLUTE MAXIMUM RATINGS (TA = 25 C UNLESS OTHERWISE NOTED) Symbol Limit Units Parameter VDS 20 Drain-Source Voltage V VGS ±8 Gate-Source Voltage o TA=25 C a Continuous Drain Current o TA=70 C b Pulsed Drain Current Continuous Source Current (Diode Conduction) a 7.8 ID IDM ±50 IS 2.3 o TA=25 C a Power Dissipation o TA=70 C THERMAL RESISTANCE RATINGS Parameter Maximum Junction-to-Ambient a Symbol t <= 10 sec Steady-State RθJA A 2.0 PD W 1.3 TJ, Tstg Operating Junction and Storage Temperature Range A 6.4 o -55 to 150 Maximum C Units 62.5 o 110 o C/W C/W Notes a.
