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 (R 3 ) 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 component cost.
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. For maximum conversion
efficiency, the ISL6263B automatically enters diode-
emulation mode (DEM) should the inductor current attempt
to flow negative. DEM is highly configurable and easy to
set-up. A PWM filter can be enabled that prevents the
switching frequency from entering the audible spectrum as a
result of 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
ISL6263B requires only one capacitor for both the soft-start
slew-rate and the dynamic VID slew-rate by internally
connecting the SOFT pin to the appropriate current source.
