AOZ1270AQI - 28V/15A Synchronous Regulator

Description

The AOZ1270AQI is a high-efficiency, easy-to-use DC/DC synchronous buck regulator that operates up to 28 V.

The device is capable of supplying 15 A of continuous output current with an output voltage adjustable down to 0.6 V ±1%.

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 AOZ1270AQI is available in a 4 mm × 4 mm QFN22L package and is rated over a -40°C to +85°C ambient temperature range. Features.
  • Wide input voltage range - 6.5 V to 28 V.
  • 15 A continuous output current.
  • Output voltage adjustable down to 0.6 V (±1.0%).
  • Low RDS(ON) internal NFETs - 11 m.

ALPHA & OMEGA SEMICONDUCTOR AOZ1270AQI 28 V/15 A Synchronous EZBuckTM Regulator General Description The AOZ1270AQI is a high-efficiency, easy-to-use DC/DC synchronous buck regulator that operates up to 28 V. The device is capable of supplying 15 A of continuous output current with an output voltage adjustable down to 0.6 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 3.5 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.
