AOZ1280集成電路（IC）的穩(wěn)壓器-DC-DC開關穩(wěn)壓器規(guī)格書PDF中文資料

General Description

The AOZ1280 is a high efficiency, simple to use, 1.2 A

buck regulator which is flexible enough to be optimized

for a variety of applications. The AOZ1280 operates from

a 3 V to 26 V input voltage range, and provides up to

1.2 A of continuous output current. The output voltage is

adjustable down to 0.8 V. The fixed 1.5 MHz PWM

switching frequency reduces inductor size.

The AOZ1280 comes in a SOT23-6L package and is

rated over a -40 °C to +85 °C operating ambient

temperature range.
