AOZ6605PI-1

EZBuck™ DC-DC Buck Regulators

Status: Full Production

The AOZ6605PI-1 is a 18V input, 5A synchronous buck regulator in a thermally enhanced SO-8 package. It has low on resistance for power switches, 55mΩ for High-Side and 26mΩ for Low-Side. The output voltage is adjustable down to 0.8V and the switching frequency is 600kHz. It features Pulse Energy Mode (PEM) to enable high efficiency in light load conditions.
