Non isolated inductive step-down converters designed with integrated solutions similar to TPS6287x are using only a few passive components to complete the circuit. Usually this is already a small design. In some cases, the passive components are still too large or just too high to fit in the application environment or the current rating of suitable components is not sufficient. To address this, multiple converters can be operated in parallel to supply the same load. Devices of the TPS6287x family support this type of configuration. Those devices have functions integrated which facilitate operating the devices in a stack in parallel. This application note describes in detail how such a stacked configuration compares to a single converter solution.
