RT8800 - Richtek Technology

RT8800 General Purpose 2/3-Phase PWM Controller

The RT8800/B 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 www.DataSheet4U.com a single analog .
