AOZ1233-01
28V/8A Synchronous EZBuck TM Regulator
General Description
The AOZ1233-01 is a high-efficiency, easy-to-use DC/DC
synchronous buck regulator that operates up to 28V.
The device is capable of supplying 8A of continuous
output current with an output voltage adjustable down to
0.8V (±1.0%).
The AOZ1233-01 integrates an internal linear regulator
to generate 5.3V V CC from input. If input voltage is lower
than 5.3V, the linear regulator operates at low drop-
output mode, which allows the V CC 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
V CC under-voltage lockout, cycle-by-current limit, output
over-voltage protection, short-circuit protection, as well
as thermal shutdown.
The AOZ1233-01 is available in a 5mm x 5mm QFN-30L
package and is rated over a -40°C to +85°C ambient
temperature range.
