A multi-module DC-DC converter provides synchronization between modules based on identification of a module within a chain. A resistor network can be used for the chain so that each module obtains a particular voltage based on its position within the chain. A master module provides a source current to drive the chain so that each module can determine its relative position in the chain based on voltage readings. With this configuration, a master module can determine how many modules are in the chain, and each slave module can determine its relative position in the chain. The module information contributes to synchronization between the modules for use in current ripple cancellation, for example, in the multi-module DC-DC converter.
