FN6802 Rev 4.00 Apr 29, 2016 The ISL6334D controls voltage regulator 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 requires high efficiency at light load. The ISL6334D utilizes Intersil’s proprietary Active Pulse Positioning (APP), Adaptive P.
