AOZ2151PQI-03 - Alpha & Omega Semiconductors

AOZ2151PQI-03 28V/4A Synchronous Regulator

The AOZ2151PQI-03 is a high-efficiency, easy-to-use DC/DC synchronous buck regulator that operates up to 28V. The device is capable of supplying 4A of continuous output current with an output voltage adjustable down to 3V to 5V. The AOZ2151PQI-03 integrates an internal linear regulator to generate 5.3V VCC from input. If input voltage is lower than 5.3V, the.
