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 Richteks 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.
