Power supply systems are often designed by paralleling converters in order to improve performance or
reliability. To ensure uniform distribution of stresses, the total load current should be equally shared
among the converters.
This application note describes a redundant system (a demo board is available) composed by three par-
alleled DC-DC converter modules (synchronous buck topology, managed by ST L6910) whose output
currents are sha
