5-Bit VID Single-Phase Voltage Regulator with Power Monitor for IMVP-6+ Santa Rosa GPU Core ISL6263ACRZ
The ISL6263A IC is a Single-Phase Synchronous-Buck PWM voltage regulator featuring Intersil's Robust Ripple Regulator (Rsup3/sup) Technology™. The ISL6263A is an implementation of the Intel® Mobile Voltage Positioning (IMVP) protocol for GPU Render Engine core power. Integrated power monitor, droop amplifier, MOSFET drivers, and bootstrap diode result in smaller implementation area and lower component cost.brbr Intersil's Rsup3/sup Technology™ combines the best features of both fixed-frequency PWM and hysteretic PWM, delivering excellent light-load efficiency and superior load transient response by commanding variable switching frequency during the transitory event. For maximum conversion efficiency, the ISL6263A automatically enters diode emulation mode (DEM) should the inductor current attempt to flow negative. DEM is highly configurable and easy to setup. A PWM filter can be enabled that prevents the switching frequency from entering the audible spectrum as a result of extremely light load while in DEM.brbr 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.
