A7131

DC-DC CONVERTER/ BUCK (STEP-DOWN)

www.ait-ic.com

3.0A 1.5MHz SYNCHRONOUS BUCK CONVERTER

DESCRIPTION

FEATURES

The A7131 is a high-efficiency, DC-to-DC step-down

switching regulators, capable of delivering up to 3.0A

of output current. The A7131 operates from an input

voltage range of 2.5V to 5.5V and provides an output

voltage from 0.6V to V_IN-0.3V, making the device

A7131 ideal for low voltage power conversions.

Running at a fixed frequency of 1.5MHz allows the

use of 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 A7131 an

ideal green replacement for large power consuming

linear regulators.
