TheAOZ2264QI-10isahigh-efficiency,easy-to-useDC/DCsynchronousbuckregulatorthatoperatesupto24V
The AOZ2264QI-10 is a high-efficiency, easy-to-use DC/
DC synchronous buck regulator that operates up to 24V.
The device is capable of supplying 15A of continuous
output current with an output voltage adjustable down to
0.6V (±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
VCCunder-voltage lockout, cycle-by-cycle current limit,
output over-voltage protection, short-circuit protection,
ａnd thermal shutdown.
The AOZ2264QI-10 is available in a 4mm x 4mm QFN-23L package and is rated over a -40°C to +85°C ambient
temperature range
