AOZ2262AQI-10
AOZ2262AQI-10
28V/10A Synchronous EZBuckTM Regulator
General Description
The AOZ2262AQI-10 is a high-efficiency, easy-to-use
DC/DC synchronous buck regulator that operates up to
28V. The device is capable of supplying 10A 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 1.3µs.
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 AOZ2262AQI-10 is available in a 4mm x 4mm QFN-
22L package and is rated over a -40°C to +85°C ambient
temperature range.
