5-Bit VID Single-Phase Voltage
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 (R3) 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 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...
