Optimized Multi-Phase PWM Controller with 6-Bit DAC and Programmable Internal Temperature Compensation for VR10.X Application
**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), channel current balancing, and overcurrent protection. To ensure the accuracy of droop, a programmable internal temperature compensation function is implemented to nullify the effect of rDS(ON) temperature sensitivity.
