RT8175A - Single-Phase Controller

Description

The RT8175A is a VR12.1 compliant CPU power controller which includes one voltage rails : a 1 phase synchronous buck controller, the CORE VR.

The RT8175A has zero load-line function to support zero load-line application.

Features

  • a quick response mechanism for optimized AVP performance during load transient. The RT8175A supports mode transition function with various operating states. A Serial VID (SVID) interface is built in the RT8175A to communicate with Intel VR12.1 compliant CPU. The RT8175A supports VID on-the-fly function with three different slew rates : Fast, Slow and Decay. By utilizing the G-NAVPTM topology, the operating frequency of the RT8175A varies with VID, load and input voltage to further enhance the ef.

® RT8175A Single-Phase Controller with Integrated Driver for VR12.1 Mobile CPU Core Power Supply General Description The RT8175A is a VR12.1 compliant CPU power controller which includes one voltage rails : a 1 phase synchronous buck controller, the CORE VR. The RT8175A has zero load-line function to support zero load-line application. The RT8175A adopts G-NAVPTM (Green Native AVP), which is Richtek's proprietary topology derived from finite DC gain compensator with current mode control, making it an easy to set the PWM controller, meeting all Intel CPU requirements of AVP (Active Voltage Positioning). Based on the G-NAVPTM topology, the RT8175A also features a quick response mechanism for optimized AVP performance during load transient.
