General Description
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 accuracy DAC achieve accurate output voltage regulation.

Features
• G-NAVPTM (Green Native Active Voltage Positioning) Topology
• Dual Output Controller with Two Built-in Gate Drivers
• Serial VID Interface
• 0.5% DAC Accuracy
• Differential Remote Output Voltage Sensing
• Built-in ADC for Platform Programming
• Diode Emulation Mode (DEM) at Light Load Condition
• Droop Enable/Disable
• Fast Transient Response
• VR12/IMVP7 Compatible Power Management States
• VR Ready Indicator
• Thermal Throttling Indicator
• Current Monitor Output
• Switching Frequency up to 1MHz per Phase
• Protection : OVP, UVP, NVP, OCP, UVLO
• Small 48-Lead WQFN Package
• RoHS Compliant and Halogen Free

Applications
• VR12 / IMVP7 Intel CPU Core Supply
• AVP Step-down Converter
• Notebook/ Netbook/ Desktop Computer CPU Core Supply
