The present invention provides a configurable dc-dc power converter module and method of manufacture for such module. The power converter module comprises an isolated subassembly with a capacitor bank, control circuits and an isolated power train that converts an input voltage to an intermediate bus voltage. The power module further comprises multiple non-isolated power trains electrically coupled to the isolated subassembly that are powered by the intermediate bus voltage to produce output voltages. The number of output voltages is determined by the number of populated non-isolated power trains, which may include all of the non-isolated power trains in the power module or a subset thereof. In one embodiment of the invention the non-isolated power trains are located on a carrier PWB that is electrically coupled to the bus PWB.
