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.
