5-Bit VID Single-Phase Voltage Regulator

with Current Monitor for GPU Core Power

Features

• Precise Single-Phase Core Voltage Regulator

- 0.5% System Accuracy 0°C to +100°C

The ISL6263C IC is a Single-Phase Synchronous-Buck

PWM voltage regulator for GPU core power application. It

- Differential Remote GPU Die Voltage Sense

features Intersil’s Robust Ripple Regulator (R )

• Real-Time GPU Current Monitor Output

• Applications up to 25A

Technology™. Integrated current monitor, differential remote

sense amplifier, MOSFET driver 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

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.

• 5-Bit Voltage Identification Input (VID)

- 0.41200V to 1.28750V

- 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

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.

• Integrated MOSFET Drivers and Bootstrap Diode

• Choice of Current Sense Schemes

- Lossless Inductor DCR Current Sense

- Precise Resistive Current Sense

• Overvoltage, Undervoltage and Overcurrent Protection

• Pb-Free (RoHS Compliant)

1. Please refer to TB347 for details on reel specifications.

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.
