ISL6565, Multi-Phase PWM Controller with Precision rDS(ON) or DCR Current Sensing for VR10.X Application

® ISL6565A, ISL6565B Data Sheet December 2003 FN9135 PRELIMINARY Multi-Phase PWM Controller with Precision rDS(ON) or DCR Current Sensing for VR10.X Application The ISL6565A, ISL6565B controls microprocessor core voltage regulation by driving up to 3 synchronous-rectified buck channels in parallel.

Multi-phase buck converter architecture uses interleaved timing to multiply channel ripple frequency and reduce input and output ripple currents.

The difference between the ISL6565A and the ISL6565
