Overview

5-Bit VID Single-PhaseVoltage Regulator for IMVP-6+ Santa Rosa GPU Core

The ISL6263DHRZ IC is a Single-Phase Synchronous-Buck PWM voltage regulator featuring Intersil’s Robust Ripple Regulator (R3) Technology™. The ISL6263DHRZ is an implementation of the Intel® Mobile Voltage Positioning (IMVP) protocol for GPU Render Engine core power. Integrated MOSFET drivers, bootstrap diode, and droop amplifier result in lower component cost and smaller implementation area. Intersil’s R3 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.
