Multiphase PWM Regulator for VR12.5, VR12.6 and VR12.6+ CPUs

Fully compliant with Intel VR12.5, VR12.6 and VR12.6+™

Features

specifications, the ISL95812 provides a complete solution for

• Serial data bus

microprocessor core power supply. It provides a Voltage

Regulator (VR) with two integrated and one external gate

drivers. The VR can be configured as 3-, 2- or 1-phase,

providing maximum flexibility. The VR uses the serial control bus

(SVID) to communicate with the CPU and achieves lower cost and

smaller board area.

• Output configurable 3-, 2- or 1-phase using two integrated

gate drivers

• Precision core voltage regulation

- 0.5% system accuracy over-temperature

- Enhanced load line accuracy

Based on Intersil’s Robust Ripple Regulator (R ) technology™,

• Supports multiple current sensing methods

- Lossless inductor DCR current sensing

- Precision resistor current sensing

the PWM modulator compared to traditional modulators, has

faster transient settling time, variable switching frequency

during load transients and has improved light load efficiency

with its ability to automatically change switching frequency.

• Differential remote voltage sensing

The ISL95812 has several other key features. The output

supports DCR current sensing with single NTC thermistor for

DCR temperature compensation or accurate resistor current

sensing. The output comes with remote voltage sense,

• Programmable V
