The ISL6334AR5368 controls 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 ponents, 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 ISL6334AR5368 utilizes Intersil’s proprietary Active Pulse Positioning (APP), Adaptive Phase Alignment (APA) modulation scheme, active phase adding and dropping to achieve and maintain the extremely fast transient response with fewer output capacitors and high efficiency from light to full load.
