AOZ2295AQI-03 Datasheet | Alpha & Omega Semiconductors

ALPHA & OMEGA SEMICONDUCTOR AOZ2295AQI-03 25V Input, 3.3V/12A Output Synchronous EZBuck TM Regulator General Description The AOZ2295AQI-03 is a high-efficiency, easy-to-use DC/ DC buck regulator that targeted for system-power supply solution. The devices are capable of supplying 12A of continuous output current with 3.3V output voltage. The AOZ2295AQI-03 integrates an internal linear regulator to generate 5.0V VCC from input. If input voltage is lower than 5.0V, the linear regulator operates at low drop output mode, which allows the VCC voltage is equal to input voltage minus the drop-output voltage of the internal linear regulator. 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 device Features multiple protection functions such as LDO under-voltage lockout, cycle-by-cycle current limit, output over-voltage protection, short-circuit protection, and thermal shutdown. The AOZ2295AQI-03 is available in a 4mm×4mm QFN - 31L package and is rated over a -40°C to +85°C ambient temperature range.
