AOZ1281

EZBuck™ 1.8 A Simple Buck Regulator

General Description

Features

The AOZ1281 is a high efficiency, simple to use, 1.8 A

buck regulator flexible enough to be optimized for a

variety of applications. The AOZ1281 works from a 3 V to

26 V input voltage range, and provides up to 1.8 A of

continuous output current. The output voltage is

z 3 V to 26 V operating input voltage range

z 240 mΩ internal NMOS

z High efficiency: up to 95 %

z Internal compensation

adjustable down to 0.8 V. The fixed switching frequency

of 1.5 MHz PWM operation reduces inductor size.

z 1.8 A continuous output current

z Fixed 1.5 MHz PWM operation

z Internal soft start

z Output voltage adjustable down to 0.8 V

z Cycle-by-cycle current limit

z Short-circuit protection

z Thermal shutdown

z Small size: DFN 2x2, 8L

Applications

z Point of load DC/DC conversion

z Set top boxes

z DVD drives and HDD

z LCD Monitors & TVs

z Cable modems

z Telecom/Networking/Datacom equipment
