AOZ1605

500 mA/3 MHz EZBuck Regulator

General Description

Features

The AOZ1605 is a high-performance, easy-to-use Buck

regulator. The 3 MHz switching frequency, low quiescent

current and small package size make it an ideal choice

for portable applications. The AOZ1605 has a patented

light load mode architecture allowing up to 85% efficiency

at 1 mA load currents, enabling longer standby times in

battery operated systems.



2.5 V to 5.5 V input voltage range

30 A quiescent current

0.05 A shutdown current

Output voltage adjustable to 0.6 V

Fixed output voltages available

± 1.5% initial accuracy

Up to 500 mA continuous output current

3 MHz constant frequency operation

Low drop-out operation: 100% duty cycle

Cycle-by-cycle current-limit

The AOZ1605 operates from a 2.5 V to 5.5 V input

voltage range and provides up to 500 mA of output

current with an output voltage adjustable down to 0.6 V.

The AOZ1605 is available in a tiny 2 mm x 2 mm 8-pin

DFN package and is rated over a -40 °C to +85 °C

ambient temperature range.

Thermal overload protection

Excellent load transient response

Internal soft-start

Tiny 2 mm x 2 mm DFN-8 package
