... ISL6558EVAL1Z - Multi-Phase Power Conversion For Routers and PC Peripherals Up To 100A Abstract This application note highlights design considerations for a 150W power supply using Intersil’s ISL6558 4-Phase Controller and ISL6612A Synchronous-Rectified Driver. A step-by-step design procedure for a 12V-to-1.5V@100A with 83% efficiency converter based on these two chips is described ...

... MOSFETs. Paralleling MOSFETs in each leg is another way to push per-phase currents even higher, but the power and thermal stresses on each driver should be evaluated carefully. In such a case driver such as Intersil’s ISL6609 could be considered. See “DRIVER LOSSES CALCULATION” on page 8. In the reference design, all four phases of the ISL6558 are used to deliver 100A of total output current ...
