AOZ2263BQI-18
Description The AOZ2263BQI-18 is a high-efficiency, easy-to-use DC/ DC synchronous buck regulator that operates up to 28 V. The device is capable of supplying 12 A of continuous output current with an output voltage adjustable down to 0.8 V ±1%. A proprietary constant on-time PWM control with input feed-forward results in ultra-fast transient response while maintaining relatively constant switching frequency over the entire input voltage range. The on time can be externally programmed up to 3.3 μS. The device features multiple protection functions such as VCC under-voltage lockout, cycle-by-cycle current limit, output over-voltage protection, short-circuit protection, and thermal shutdown. The AOZ2263BQI-18 is available in a 4 mm × 4 mm QFN-23L package and is rated over a -40°C to +85°C ambient temperature range. Features - Wide input voltage range - 10 V to 28 V - 12 A continuous output current - Output voltage adjustable from 0.8 V ±1.0% - Low RDS(ON) internal NFETs - 11 mΩ...
