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.
