AOZ1284PI
EZBuck™ DC-DC Buck Regulators
Status: Full Production
The AOZ1284PI is a 36V input, 4A 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 an adjustable PWM switching frequency that helps increase system design optimization.
