5-Bit VID Single-Phase Voltage Regulator
with Current Monitor for GPU Core Power
The ISL6263C IC is a Single-Phase Synchronous-Buck
PWM voltage regulator for GPU core power application. 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 ISL6263C 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
0.41200V to 1.28750V by the five VID input pins without
requiring sequential stepping of the VID states. The
ISL6263C 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.
