3 Voltage Identification Capability with TPS51215A

The TPS51215A supports a 2-bit Voltage Identification Capability (VID) and Low Power Mode (LPM) to dynamically change the output voltage to satisfy Intel's VCCIN_AUX rail. A fixed 0-V output voltage and up to three voltage levels can be programmed externally with a voltage divider circuit. The device can also be configured to provide a 1-bit VID output voltage. Please see the TPS51215A Single Phase, D-CAP2™ Controller with 2-Bit VID Control and Low Power Mode data sheet for more information. The Power solution for Alder Lake and Raptor Lake VCCIN_AUX rail in PC applications reference design describes how to use this device to meet Intel's VCCIN_AUX rail requirements in more detail.
