DATASHEET FN6689 Rev 3.00 May 5, 2016 The ISL6334B, ISL6334C control microprocessor core voltage regulation by driving up to 4 interleaved synchronous-rectified buck channels in parallel. This multiphase architecture results in multiplying channel ripple frequency and reducing input and output ripple currents. Lower ripple results in fewer components, lower cost, reduced power dissipation, and smaller implementation area. Microprocessor loads can generate load transients with extremely fast edge rates and require high efficiency at light load. The ISL6334B, ISL6334C utilizes Intersil’s propr.
