Abstract
Point-of-load (POL) regulators may be configured as multiphase POL DC-to-DC (direct current to direct current) converters, operating in a multiphase configuration in order to boost the total current available to a system. Current balancing may be performed by utilizing an active low bandwidth current sharing algorithm that uses matched artificial line resistance (droop resistance) while maintaining multi-loop stability during both steady-state and dynamic transient states. The current sharing algorithm may be facilitated through digital communication between the devices, where the digital bus may be a single wire bus, a parallel bus or a clock-and-data bus.
