Abstract
A large, monolithic voltage regulator module placed under an application specific integrated circuit (ASIC), e.g., on the bottom side of its printed circuit board (PCB) in a vertical power delivery configuration, can be subject to mechanical stress, creating long-term reliability problems and making socketed ASICs infeasible. This disclosure describes a modular voltage regulator, which is such that constituent modules of the voltage regulator can be placed at convenient locations below a PCB, enabling power delivery to the precise locations needed by the ASIC. The modular voltage regulator enables flexibility in design choices, reduces mechanical stress, supports multiple power rails, can deliver power to non-rectangular circuit blocks or areas, reduces re-work, improves yield, and is cheaper to replace.
