      The TPS51215A is a single-phase, D-CAP2™ synchronous buck controller with a 2-bit VID input supporting 0 V and three other independent externally programmable output voltage levels, 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 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 external programmable integrator capacitor. The TPS51215A provides full protection suite, including OVP, OCL, 5-V UVLO and thermal shutdown. It supports the conversion voltage up to 28 V, and output voltages adjustable from 0.5 V to 2 V.

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