DESCRIPTION

The A7115B is a 2MHz high-efficiency, PWM

step-down converter with integrated main

switch and synchronous rectifier that is ideal for

powering portable equipment that runs from a

single Li-on or Li-Polymer battery.

The A7115B can supply up to up to 1.5A load

current from a 2.6V to 5.5V input voltage. The

output voltage can be as low as 0.6V.

The A7115B features include <1uA shutdown

current, small external components, such as

ceramic input and output caps, as well as small

inductors, while still providing low output

ripples. This low noise output along with its

excellent efficiency achieved by the internal

synchronous rectifier, making A7115B an ideal

replacement for large power consuming linear

regulators. Internal soft-start control circuitry

reduces inrush current. Short-circuit and

thermal shutdown protection improves design

reliability.

The A7115B is available in SOT-25 and DFN6

(2x2) packages.

APPLICATION

? Cellular phones

? Microprocessors and DSP Core Supplies

? PDA and Smart Phones

? MP3 and Portable Media Players

? Digital Still and Video Cameras

? Portable Instruments

? Set Top Box

? Wireless and DSL modems

? USB supplied devices in notebooks
