General Description
The AOZ2231CQI-11 is an I2C controllable, high
efficiency, easy-to-use DC-DC synchronous buck
regulator capable of operation from a 6.5V to 28V input
bus. Ability to control the output voltage using the I2C bus
simplifies converter design for microprocessors or SoCs
that require dynamic voltage scaling or voltage
margining. The device is capable of supplying 4A of
continuous output current with an output voltage
adjustable from 0.9V to 1.190625V (±2.0).
The AOZ2231CQI-11 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 devices feature 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 AOZ2231CQI-11 is available in a 4mm×4mm QFN-
22L package and is rated over a -40°C to +85°C ambient
temperature range.
