The AOZ1236-01 is a high-efficiency, easy-to-use DC/DC
synchronous buck regulator that operates up to 28V.
The device is capable of supplying 6A of continuous
output current with an output voltage adjustable down to
0.8V (±1.0%).
The AOZ1236-01 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 dropoutput
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 switching frequency
can be externally programmed up to 1MHz.
The device features multiple protection functions such as
VCC under-voltage lockout, cycle-by-cycle current limit,
output over-voltage protection, short-circuit protection, as
well as thermal shutdown.
The AOZ1236-01 is available in a 4mm x 4mm QFN-23L
package and is rated over a -40°C to +85°C ambient
temperature range.
