MC4609 Datasheet PDF - Freescale Semiconductor

P & N-Channel  30-V (D-S) MOSFET

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 PWM DC-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
