The ISL6336B controls microprocessor core voltage regulation by driving up to 6 interleaved synchronous-rectified buck channels in parallel.
Multiphase buck converter architecture uses interleaved timing to multiply channel ripple frequency and reduce input and output ripple currents.
Lower ripple results in fewer components, lower component cost, reduced power dissipation, and smaller implementation area.
Microprocessor loads can generate load transients with extremely fast edge rates and require high efficiency over the full load range.
The ISL6336B utilizes Intersil’s proprietary Active Pulse Positioning (APP) and Adaptive Phase Alignment (APA) modulation scheme and a proprietary active phase dropping/adding and diode emulation scheme to a...
