AOZ1282DI
EZBuck™ DC-DC Buck Regulators
Status: Full Production
The AOZ1282DI is a 36V input, 1.2A non-synchronous buck regulator in a thermally enhanced DFN2x2 package. It is offered in a wide input range from 4.5V to 36V, and the output voltage is adjustable down to 0.8V. It features a fixed 450kHz PWM switching frequency that facilitates a simplified system design.
