TPS 51518

The TPS51518 is a single phase, D-CAP/D-CAP2 synchronous buck controller with 2-bit VID inputs which can select up to four independent externally programmable output voltage levels where full external programmability in the voltage level, step setting and voltage transition slew rate is desired. It is used for GFX applications where multiple voltage levels are desired.The TPS51518 supports all PS/SPCAP and/or all ceramic MLCC output capacitor options in applications where remote sense is a requirment. Tight DC load regualtion is achieved through external programmable inegrator capacitor.The TPS51518 provides full protection suite, including OVP, OCL, 5V ULVO and thermal shutdown. It supports the conversion voltage up to 28V, and output voltages adjustable from 0.5V to 2V.The TPS51518 is available in the 3mm x 3mm, QFN, 0.40mm pitch package and is specified from -10C to 105C.
