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.
