AOZ1232-01
28V/6A Synchronous EZBuckTM
Regulator
General Description
The AOZ1232-01 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 AOZ1232-01 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-current limit, output over-voltage protection, short-circuit protection, as well as thermal shutdown. The AOZ1232-01 is available in a 5mm x 5mm QFN-30L package and is rated over a -40°C to +85°C ambient temperature range.
