Optimized Multiphase PWM Controller with 6-Bit DAC for VR10.X Application
FN9096 Rev 3.00 December 29, 2004
The ISL6556A 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. Lower ripple results in fewer ponents, lower ponent cost, reduced power dissipation, and smaller implementation area.
The ISL6556A utilizes rDS(ON)...
