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
3
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
