Description
The RT8800, RT8800B are general purpose multi-phase synchronous buck controllers dedicating for high density power supply regulation.
The parts implement 2, and 3 buck switching stages operating in interleaved phase set automatically. The output voltage is regulated and controlled following the input voltage of FB pin.
With such a single analog control, the RT8800/B provide a simple, flexible, wide-range and extreme cost-effective high density voltage regulation solutions for various high-density power supply application.
Features
