5-Bit VID Single-Phase Voltage Regulator

with Current Monitor for IMVP-6+ Santa

Rosa GPU Core

Features

• Precision single-phase core voltage regulator

- 0.5% system accuracy 0°C to +100°C

- Differential remote GPU die voltage sensing

- Differential droop voltage sensing

The ISL6263B IC is a Single-Phase Synchronous-Buck

PWM voltage regulator featuring Intersil’s Robust Ripple

Regulator (R ) Technology™. The ISL6263B is an

• Real-time GPU current monitor output

• Applications up to 25A

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.

• Input voltage range: +5.0V to +25.0V

• Programmable PWM frequency: 200kHz to 500kHz

• Pre-biased output start-up capability

Intersil’s R Technology™ combines the best features of

• 5-bit voltage identification input (VID)

- 1.28750V to 0.41200V

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.

- 25.75mV steps

- Sequential or non-sequential VID change on-the-fly

• Configurable PWM modes

- forced continuous conduction mode

- automatic entry and exit of diode emulation mode

- selectable audible frequency PWM filter

• Integrated MOSFET drivers and bootstrap diode

• Choice of current sensing schemes

- Lossless inductor DCR current sensing

- Precision resistive current sensing

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.

Processor socket Kelvin sensing is accomplished with an

integrated unity-gain true differential amplifier.

• Overvoltage, undervoltage and overcurrent protection

• Pb-free (RoHS compliant)

2. These Intersil Pb-free plastic packaged products employ special Pb-

free material sets, molding compounds/die attach materials, and

100% matte tin plate plus anneal (e3 termination finish, which is RoHS

compliant and compatible with both SnPb and Pb-free soldering

operations). Intersil Pb-free products are MSL classified at Pb-free

peak reflow temperatures that meet or exceed the Pb-free

requirements of IPC/JEDEC J STD-020.
