AOZ1284

EZBuck™ 4A Simple Buck Regulator

General Description

Features

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.



3.0V to 36V operating input voltage range

50mΩ internal NMOS

Efficiency up to 95%

Adjustable soft-start

Output voltage adjustable from 0.8V to 30V

4A continuous output current

Adjustable switching frequency from 200kHz to

2MHz

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.



Cycle-by-cycle current limit

Short-circuit protection

Over-voltage protection

Over-temperature protection

EPAD SO-8 package

Applications



Point of load DC/DC conversion

Set top boxes and cable modems

Automotive applications

DVD drives and HDDs

LCD Monitors & TVs

Telecom/Networking/Datacom equipment

Typical Application
