Texas Instruments TPS51215A Single-Phase D-CAP2™ Buck Controller is a controller with a 2-bit VID input supporting 0V and three other independent externally programmable output voltage levels. These are ideal where full external programmability of the voltage level, step setting, and voltage-change slew rate is desired. It is used for Intel IMVP8/9 applications, where multiple voltage levels are desired.
The Texas Instruments TPS51215A supports all POS/SPCAP and/or all-ceramic MLCC output capacitor options in applications where remote sense is a requirement. Tight DC load regulation is achieved through an external programmable integrator capacitor. The TPS51215A provides full protection suite, including OVP, OCL, 5V UVLO, and thermal shutdown. It supports the conversion voltage up to 28V, and output voltages adjustable from 0.5V to 2V.

The TPS51215A is available in the 3mm × 3mm, QFN, 0.4mm pitch package and is specified from –40°C to 125°C.
