RT8167AGQW

® RT8167A Dual Single-Phase PWM Controller for CPU Core/GFX Power Supply General Description Features 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. z 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 proprietary G-NAVPTM (Green Native AVP) makes AVP (Active Voltage Positioning) design easier and more robust. By utilizing the G-NAVPTM topology, DEM and CCM efficiency can be improved. z z z z z z z z z z z z 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 and GFX 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 z z z Applications z z z Marking Information 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 VR12 / IMVP7 Intel CPU Core Supply AVP Step-down Converter Notebook/ Netbook/ Desktop Computer CPU Core Supply RT8167AGQW : Product Number RT8167A GQW YMDNN YMDNN : Date Code Ordering Information RT8167A Package Type QW : WQFN-48L 6x6 (W-Type) (Exposed Pad-Option 1) Lead Plating System G : Green (Halogen Free and Pb Free) Note : Richtek products are : ` RoHS compliant and compatible with the current requirements of IPC/JEDEC J-STD-020. ` Copyright © 2014 Richtek Technology Corporation.
