Part Number : ISL6260
Function : Multiphase PWM Regulator for IMVP-6+ Mobile CPUs
Manufacturers : Intersil
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 thispower 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.
