Introduction

AI Translation

The AOZ2263VQI-02 is a high-efficiency, easy-to-use DC/DC synchronous buck regulators capable of operation from a 4V to 28V input bus. The device is capable of supplying 12A of continuous output current with an output voltage adjustable from 0.8V to 1.05V by controlling VID0 and VID1 signals. Constant on-time PWM with input feed-forward control scheme results in ultra-fast transient response while maintaining relatively constant switching frequency over the entire input range. True AC current mode control scheme guarantees the regulators can be stable with ceramics output capacitor. Protection features include VCC under-voltage lockout, cycle-by-cycle current limit, output over voltage and under voltage protection, shortcircuit protection, and thermal shutdown. The AOZ2263VQI-02 is available in 22-pin 4mmx4mm QFN package.
