AOZ2261NQI
Alpha & Omega Semiconductor
28V/8A Synchronous EZBuckTM Regulator
Package Type : 4x4 QFN-22L
The AOZ2261QI-15 is a high-efficiency, easy-to-use DC/ DC synchronous buck regulator that operates up to 28V. The device is capable of supplying 8A of continuous output current with an output voltage adjustable down to 0.8V (±1.0%). 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 2.6µs. 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 AOZ2261QI-15 is available in a 4mm x 4mm QFN22L package and is rated over a -40°C to +85°C ambient temperature range.
