AOZ2367QI-11 24V/20A Synchronous EZBuckTM Regulator General Description Features The AOZ2367QI-11 is a high-efficiency, easy-to-use DC/
DC synchronous buck regulator that operates over a
wide 4.5V to 24V voltage range.The device is capable of
supplying 20A of continuous output current with an
output voltage adjustable down to 0.6V (±1.0%).  Wide input voltage range 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. A low 80ns minimum ontime enables very low output voltages at ultra-high
operating frequencies.
Integrated AC ripple injection enables all-ceramic low
ESR output filter capacitors and smaller PCB footprint
with no external components needed. – 4.5V to 24V
 20A continuous output current
 Output voltage adjustable down to 0.6V (±1.0%)
 Low RDS(ON) internal NFETs – 4m high-side
– 3m low-side
 Constant On-Time with input feed-forward
 Programmable on-time up to 2.6µs and down to 80ns
 Programmable switching frequency range: 32kHz to 1MHz (for 12VIN to 1VOUT)
 Selectable PFM or forced PWM light load operation
 Ceramic capacitor stable Selectable PFM mode optimizes light load efficiency
while forced PWM mode maintains constant frequency
for lower harmonic noise.  Adjustable soft start The device features multiple protection functions such as …
