Multiphase buck controller
Maturity plannedTargets ASIC (CMOS) onlyDifficulty Very hardPriority 2
Interleaved multiphase step-down controller with phase current balancing and dynamic phase shedding for processor core rails.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
