5-Bit VID Single-Phase Voltage Regulator with Current Monitor for IMVP-6+ Santa Rosa GPU Core
The ISL6263B IC is a Single-Phase Synchronous-Buck PWM voltage regulator featuring Intersil’s Robust Ripple Regulator (R3) Technology™. The ISL6263B is an implementation of the Intel® Mobile Voltage Positioning (IMVP) protocol for GPU Render Engine core power. Integrated current monitor, droop amplifier, MOSFET drivers and bootstrap diode result in smaller implementation area and lower ponent cost. Intersil’s R3 Technology™ bines the best Features of both fixed-frequency PWM and hysteretic PWM, delivering excellent light-load efficiency and...
