5-Bit VID Single-PhaseVoltage Regulator for IMVP-6+ Santa Rosa GPU Core
**The ISL6263 IC is a Single-Phase Synchronous-Buck PWM voltage regulator
featuring Intersil’s Robust Ripple Regulator (R 3 ) Technology™. The ISL6263 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 R 3 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.Features
