AOZ1283PI

EZBuck™ DC-DC Buck Regulators

Status: Full Production

The AOZ1283PI is a 36V input, 2.5A non-synchronous buck regulator in a thermally enhanced SO-8 package. It is offered in a wide input range from 3V to 36V, and the output voltage is adjustable down to 0.8V. It features adjustable PWM switching frequency that helps increase system design optimization.
