RT8167A

Dual Single-Phase PWM Controller for CPU Core/GFX

Power Supply

General Description

Features

^zG-NAVP^TM(GreenNativeActive Voltage Positioning)

The RT8167A is a dual single-phase synchronous Buck

PWM controller with integrated gate drivers, compliant

with Intel VR12/IMVP7 specification. A serial VID (SVID)

interface is built-in in the RT8167A to communicate with

Intel VR12/IMVP7 compliant CPU. The integrated

differential remote output voltage sensing function and

built-in high accuracyDAC achieve accurate output voltage

regulation.

Topology

^zDual Output Controller with Two Built-in Gate

Drivers

^zSerial VID Interface

^z0.5% DAC Accuracy

^zDifferential Remote Output Voltage Sensing

^zBuilt-in ADC for Platform Programming

^zDiode Emulation Mode (DEM) at Light Load

Condition

The RT8167A supports VR12/ IMVP7 compatible power

management states and VID on-the-fly function. The

RT8167A operates in two power management states

including DEM in PS2 and Forced-CCM in PS1/PS0.

Richtek's proprietaryG-NAVP^TM(GreenNativeAVP) makes

AVP (Active Voltage Positioning) design easier and more

robust. By utilizing theG-NAVP^TMtopology,DEM and CCM

efficiency can be improved.

^zDroop Enable/Disable

z Fast Transient Response

z VR12/IMVP7 Compatible Power Management

States

z VR Ready Indicator

z Thermal Throttling Indicator

z Current Monitor Output

The RT8167A integrates high accuracy ADC for platform

setting functions, such as no-load offset or over current

level. Individual VR ready output signals are provided for

both CORE VR andGFX VR. The IC also features complete

fault protection functions, including over voltage, under

voltage, negative voltage, over current and under voltage

lockout. The RT8167A is available in a WQFN-48L 6x6

small foot print package.

z Switching Frequency up to 1MHz per Phase

z Protection : OVP, UVP, NVP, OCP, UVLO

z Small 48-Lead WQFN Package

z RoHS Compliant and Halogen Free

Applications

z VR12 / IMVP7 Intel CPU Core Supply

z AVP Step-down Converter

z Notebook/ Netbook/ Desktop Computer CPU Core

Supply
