Rev 0.00
March 5, 2013 Multiphase PWM Regulator for VR12.5, VR12.6 and VR12.6+ CPUs Features Fully compliant with Intel VR12.5, VR12.6 and VR12.6+^TM
specifications, the ISL95812 provides a complete solution for
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. • Serial data bus
• 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
• Supports multiple current sensing methods
-Lossless inductor DCR current sensing
-Precision resistor current sensing Based on Intersil's Robust Ripple Regulator (R3) technology^TM,
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 …
