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 …
