Description

The RT8171C is a VR12.1 compliant CPU power controller which includes one voltage rails : a 1 phase synchronous buck controller, the CORE VR. The RT8171C has zero load-line function to support zero load-line application. The RT8171C 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 RT8171C also features a quick response mechanism for optimized AVP performance during load transient. The RT8171C supports mode transition function with various operating states. A Serial VID (SVID) interface is built in the RT8171C to communicate with Intel VR12.1 compliant CPU. The RT8171C 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 RT8171C varies with VID, load and input voltage to further enhance the efficiency even in CCM. The built-in high accuracy DAC converts the SVID code ranging from 0.25V to 1.52V with 5mV per step, as shown in Table 1. The RT8171C integrates a high accuracy ADC for platform setting functions, such as quick response or over current level. The RT8171C provides VR ready output signals. It also features complete fault protection functions including Over Voltage (OV), Under Voltage (UV), Negative Voltage (NV), Over Current (OC) and Under Voltage Lockout (UVLO).
