ISL6556B NOT RECOMMENDED FOR NEW DESIGNS NO RECOMMENDED REPLACEMENT contact our Technical Support Center at 1-888-INTERSIL or www.intersil.com/tsc Optimized Multi-Phase PWM Controller with 6-Bit DAC and Programmable Internal Temperature Compensation for VR10.X Application DATASHEET FN9097 Rev 4.00 December 28, 2004 The ISL6556B controls microprocessor core voltage regulation by driving up to 4 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 ISL6556B utilizes rDS(ON) current sensing in each phase for adaptive voltage positioning (droop), channelcurrent balancing, and overcurrent protection.
