AOS AOZ1282CI

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.

The AOZ1282CI is a current - mode step down regulator with integrated high side NMOS switch. It operates from a 4.5V to 36V input voltage range and supplies up to 1.2A of load current. Features include enable control, under voltage lock - out, internal soft - start, output overvoltage protection, over - current protection and thermal shut down.

The AOZ1282CI is available in SOT23 - 6L package.
