RT8845A Multi-Phase PWM Controller

RT8845A Description

® RT8845A Multi-Phase PWM Controller with PWM-VID Reference General .
The RT8845A is a 4/3/2/1 phase synchronous Buck PWM controller which is optimized for high performance graphic microprocessor and computer application.

RT8845A 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/external soft- start, power good indicator, and en

RT8845A Applications

* The RT8845A adopts G-NAVPTM (Green Native AVP) which is Richtek's proprietary topology derived from finite DC gain of EA amplifier with current mode control. By utilizing the GNAVPTM topology, the operating frequency of the RT8845A varies with VID, load and input voltage to further enhance the effi
