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
(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.
To maximize light load efficiency, the ISL6263 automatically
transitions between continuous-conduction-mode (CCM)
and discontinuous-conduction-mode (DCM.) During DCM
the low-side MOSFET enters diode-emulation-mode (DEM.)
DEM is enabled whenever a Render Suspend state has
been set on the VID inputs. Optionally, DEM can be enabled
for all VID states by setting the FDE pin high. The ISL6263
has an audio filter that can be enabled in any Render
Suspend state by pulling the AF_EN pin high. The audio
filter prevents the PWM switching frequency from entering
the audible spectrum due to extremely light load while in
DEM.
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
ISL6263 uses the same capacitor for the soft-start slew-rate
and for 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
