RT8175A

Single-Phase Controller with Integrated Driver for VR12.1

Mobile CPU Core Power Supply

General Description

Features

^VR12.1 Compatible Power Management States

^Switching Frequency up to 1MHz

^Serial VID Interface

The RT8175Ais 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

RT8175AadoptsG-NAVP^TM(GreenNativeAVP), which is

Richtek's proprietary topology derived from finiteDC gain

compensator with current mode control, making it an easy

to set the PWM controller, meeting all Intel CPU

requirements ofAVP (Active Voltage Positioning). Based

on theG-NAVP^TMtopology, the RT8175Aalso features a

quick response mechanism for optimizedAVP 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-NAVP^TMtopology, the operating frequency of the

RT8175Avaries with VID, load and input voltage to further

enhance the efficiency even in CCM. The built-in high

accuracyDAC converts the SVIDcode ranging from 0.25V

to 1.52V with 5mV per step, as shown in Table 1. The

RT8175A integrates a high accuracy ADC for platform

setting functions, such as quick response or over current

level. The RT8175A 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). The RT8175A is available in a WQFN-32L 4x4

small foot print package.
