AOZ1081

EZBuck™ 1.8A High Efficiency

Constant Current Regulator for LEDs

General Description

The AOZ1081 is a high efficiency, simple to use, 1.8A

buck regulator for White LED. The AOZ1081 works from

a 4.5V to 16V input voltage range, and provides up to

1.8A of continuous output current with an output voltage

adjustable down to 0.25V.

The AOZ1081 comes in an SO-8 package and is rated

over a -40°C to +85°C ambient temperature range.

Features

● 4.5V to 16V operating input voltage range

● 100 mΩ internal PFET switch for high efficiency:

up to 95%

● Internal Schottky Diode

● Internal soft start

● 0.25V internal reference with ±5% accuracy over

temperature

● 1.8A continuous output current

● Fixed 1MHz PWM operation

● Cycle-by-cycle current limit

● Short-circuit protection

● Under voltage lockout

● Output over voltage protection

● Thermal shutdown

● Small size SO-8 package

Applications

● Buck regulator for white LEDs

● Landscape lighting

● Flashlights

● Battery powered backlight applications
