AOZ1282CI
EZBuck™ 1.2A Simple Buck Regulator
General Description
The AOZ1282CI is a high efficiency, simple to use, 1.2A buck regulator flexible enough to be optimized for a variety of applications. The AOZ1282CI works from a 4.5V to 36V input
voltage range, and provides up to 1.2A of continuous output current. The output
voltage is adjustable down to 0.8V. The fixed switching frequency of 450kHz PWM operation reduces inductor size.
