AOZ2263BQI-18 - Alpha & Omega Semiconductors

AOZ2263BQI-18 28V/12A Synchronous Regulator

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 .

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
