DATASHEET ISL6260, ISL6260B Multiphase Core Regulator for IMVP-6 Mobile CPUs FN9162 Rev 1.00 Jan 3, 2006 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 implementati

ISL6260 Features

* 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 th
