3 Voltage Identification (VID) with TPS51215A

The TPS51215A supports a 2-bit VID and Low Power Mode(LPM) to dynamically change the output voltage and satisfy Intel's IMVP8/9 applications for VCCIN_AUX, VCCIO_0, and VCCIO_1_2 rails. A fixed 0V output voltage and up to three voltage levels can be programmed externally by a voltage divider circuit. The device can also be configured to provide a 1-bit VID voltage. In the applications where fewer than four input voltage levels are needed, the remaining input voltage pins cannot be left floating. Please see the TPS51215A datasheet for more information.
