Data Sheet ISL6260, ISL6260B January 3, 2006 FN9162.1 Multiphase Core Regulator for IMVP-6 Mobile CPUs The ISL6260 and ISL6260B provide microprocessor core voltage regulation by driving up to 3 channels in parallel. The multiphase buck converter architecture uses interleaved channels to multiply the output voltage ripple frequency and reduce output channel currents. The reduction in ripple results in fewer components, lower component cost, reduced power dissipation, and smaller implementation area. The ISL6260, ISL6260B multiphase controller together with the ISL6208 gate drivers form the basis for a portable power supply solution to power Intel's next generation mobile microprocessors. The modulator at the heart of this power system is derived from Intersil's Robust Ripple Regulator technology, R3 Compared with the traditional multiphase buck regulator, the R3 technology multiphase converter has faster transient response. This is due to the R3 modulator commanding variable switching frequency during load transients. Intel Mobile Voltage Positioning is a smart voltage regulation technology, which effectively reduces power dissipation in Intel Pentium processors. The ISL6260 and ISL6260B support the IMVP-6 mobile processor voltage regulation specifications. ISL6260 and ISL6260B are pin-to-pin compatible. ISL6260B responds to PSI# signal by adding or dropping PWM2 and adjusting overcurrent protection accordingly.

Current sensing can be done using either DCR sensing or discrete precision resistor sensing. A single NTC thermistor thermally compensates both the gain and time constant of the DCR variation. A unity gain, differential amplifier is provided for remote CPU die sensing. This allows the voltage on the CPU die to be accurately measured and regulated per Intel IMVP-6 specifications.
