AM4919P

P-Channel 20-V (D-S) MOSFET

These miniature surface mount MOSFETs utilize

High Cell Density process. Low r_DS(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.
