General Description
The AOZ2254TQI-20 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).
The AOZ2254TQI-20 integrates an internal linear
regulator to generate 5.3V VCC from input. If input
voltage is lower than 5.3V, 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
VCC under-voltage lockout, cycle-by-cycle current limit,
output over-voltage protection, short-circuit protection,
and thermal shutdown.
The AOZ2254TQI-20 is available in a 4mm x 4mm QFN-
22L package and is rated over a -40°C to +85°C ambient
temperature range.
