® 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 ISL6565B is that the ISL6565A utilizes rDS(ON) current sensing, while the ISL6565B utilizes DCR current sensing for each phase. These cost and space saving methods of current sensing are used for adaptive voltage positioning (droop), channelcurrent balancing, and over-current protection.
