There are many ways to generate all of the DC supply rail voltages required for a given electronic design. Often a single, off-the-shelf, mains-connected converter provides the internal power system with a single DC voltage, isolated from the hazardous line from which additional rails can be generated with internal DC/DC converters.
These DC/DC converters can either be designed and built with discrete components or purchased as pre-designed modules that mount directly onto the PCB or somewhere else within the chassis. Designing in a single, off-the-shelf, mains-connected converter with multiple outputs is also an option. In rarer cases, a designer may elect to utilize multiple mains-connected converters to generate some or all the required system voltages. When no readily implementable arrangement of these options adequately meets the design requirements, the designer may seek out the design of a custom power supply.
