A7122A

DC-DC CONVERTER BUCK (STEP-DOWN)

5.5V 2A 1.3MHz SYNCHRONOUS

AiT Semiconductor Inc.

DESCRIPTION

FEATURES

The A7122A is

high-efficiency, DC-to-DC



High Efficiency: Up to 97%

Capable of Delivering 2A

step-down switching regulators, capable of delivering

up to 2A of output current. The device operates from

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

an output voltage from 0.6V to V_IN, making the

A7122A ideal for low voltage power conversions.

Running at a fixed frequency of 1.3MHz 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 A7122A an

ideal green replacement for large power consuming

linear regulators. Internal soft-start control circuitry
