General Description

The AP6015 is the first device in a family of low-noise current mode synchronous step-down DC-DC converters. It is ideally suited for systems powered by either a 1-cell Li-ion battery or a 2- to 3-cell NiCd/ NiMH/ Alkaline battery.

Features

◾ High efficiency synchronous step-down converter with greater than 94

◾ Current Mode Operation for faster transient response and better loop stabilization

◾ 2.5V to 5.5V operating input voltage range

◾ Adjustable output voltage range from 0.8V to VIN

◾ Fixed output voltage options: 1.8V, 2.5V and 3.3V

◾ Up to 800mA output current

◾ High efficiency over a wide range of load currents

◾ PWM operation mode

◾ Internal soft-start function

◾ Typical quiescent current of 150μA

◾ MSOP-10L: Available in “Green” Molding Compound (No Br, Sb)

◾ Lead Free Finish/ RoHS Compliant (Note 1)

Applications

◾ Mobile Handsets

◾ PDAs, Ultra Mobile PCs

◾ Portable Media Players, Digital Still/Video Cameras

◾ USB-based DSL Modems

◾ LAN/WLAN/WPAN/WWAN Modules
