Descrizione

Traduzione AI

The AOZ2253TQI-11 is a high-efficiency, easy-to-use, synchronous buck regulator optimized for notebook computers. The regulator is capable of supplying 8A of continuous output current with an output voltage adjustable down to 0.8V. The input voltage can be as low as 6.5V and the highest can be 28V. 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 regulator can be stable with ceramics output capacitor. Protection features include VCC under-voltage lockout, current limit, output over voltage and under voltage protection, short-circuit protection, and thermal shutdown. The AOZ2253TQI-11 is available in 22-pin 4mm×4mm QFN package.
