TheAOZ2261QI-11isahigh-efficiency,easy-to-useDC/DCsynchronousbuckregulatorthatoperatesupto28V
The AOZ2261QI-11 is a high-efficiency, easy-to-use DC/
DC synchronous buck regulator that operates up to 28V.
The device is capable of supplying 8A of continuous
output current with an output voltage adjustable down to
0.8V ±1%.
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 2.6uS.
The device features multiple protection functions such as
VCCunder-voltage lockout, cycle-by-cycle current limit,
output over-voltage protection, short-circuit protection,
ａnd thermal shutdown.
The AOZ2261QI-11 is available in a 4mm×4mm QFN-22L package and is rated over a -40°C to +85°C ambient
temperature range
