RT8820A Datasheet (Richtek) - Dual-Phase PWM Controller

RT8820A, Dual-Phase PWM Controller

The RT8820A is a 2/1 phase synchronous Buck PWM controller which is optimized for high performance graphic microprocessor and computer applications.

The IC integrates a Constant-On-Time (COT) PWM controller, two MOSFET drivers with internal bootstrap diodes, as well as channel current balance and pr

RT8820A Features

* external reference input and PWMVID dynamic output voltage control, in which the feedback voltage is regulated and tracks external input reference voltage. Other features include adjustable switching frequency, dynamic phase number control, internal softstart, power good indicator, and enable functi
