General Description

The AOZ1283 is a high voltage, high efficiency, simple to

use, 2.5A buck regulator optimized for a variety of

applications. The AOZ1283 works from a 3.0V to 36V

input voltage range, and provides up to 2.5A of

continuous output current. The output voltage is

adjustable from 30V down to 0.8V.

The AOZ1283 integrates an N-channel high-side power

MOSFET. The switching frequency can set from 200kHz

to 2MHz with an external resistor. The soft-start time can

be set with an external capacitor.
