EZBuck™ 3A Simple Buck Regulator

General Description

Features

The AOZ1242 is a high efficiency, simple to use, 3A buck

regulator flexible enough to be optimized for a variety of

applications. The AOZ1242 works from a 4.5V to 32V

input voltage range, and provides up to 3A of continuous

output current on each buck regulator output. The output

voltage is adjustable down to 0.8V.

● 4.5V to 32V operating input voltage range

● 70mΩ internal NFET, efficiency: up to 95%

● Internal soft start

● Output voltage adjustable down to 0.8V

● 3A continuous output current

● Fixed 370kHz PWM operation

● Cycle-by-cycle current limit

The AOZ1242 comes in an SO-8 or DFN-8 package and

is rated over a -40°C to +85°C ambient temperature

range

● Short-circuit protection

● Thermal shutdown

● Small size, SO-8 or DFN-8 package

Applications
