AOZ1280

AOZ1280 EZBuck™ 1.2 A Simple Buck Regulator 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.
