3-Bit VID Single-Phase Voltage Regulator
with Current Monitor for GPU Core Power
The ISL6263D IC is a Single-Phase Synchronous Buck PWM
voltage regulator for GPU core power applications. It features
Intersil’s Robust Ripple Regulator (R 3 ) Technology?.
Integrated current monitor, differential remote sense amplifier,
MOSFET driver 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 ISL6263D automatically enters Diode
Emulation Mode (DEM) when the inductor current attempts
to flow negative. DEM is highly configurable and easy to
set-up. A PWM filter can be enabled, which prevents the
switching frequency from entering the audible spectrum as a
result of extremely light load while in DEM.
The GPU core voltage can be dynamically programmed from
0.7V to 1.0875V by the three VID input pins without requiring
sequential stepping of the VID states. The ISL6263D
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. The voltage
Kelvin sensing is accomplished with an integrated unity-gain
true differential amplifier.
