The AOZ1284 is a high voltage, high efficiency,
simple to use, 4A buck regulator optimized for a
variety of applications. The AOZ1284 works from a
3.0V to 36V input voltage range, and provides up to
4A of continuous output current. The output voltage
is adjustable from 30V down to 0.8V.
The AOZ1284 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.
