VDD 2 VSS SOFT VIN 24 VID1 VSUM 1 VO RBIAS DFB The Render core voltage can be dynamically programmed
from 0.41200V to 1.28750V by the five VID input pins
without requiring sequential stepping of the VID states. The
ISL6263A requires only one capacitor for both the soft-start
slew-rate and the dynamic VID slew-rate by internally
connecting the SOFT pin to the appropriate current source.
Processor socket Kelvin sensing is accomplished with an
integrated unity-gain true differential amplifier. Precision Single-phase Core Voltage Regulator
