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
