Abstract: At least one aspect is directed to a power supply. The power supply includes one or more unregulated voltage converters. Each unregulated voltage converter includes a switched block producing an output voltage across its output terminals. The power supply includes a voltage supply input coupled to at least one of the unregulated voltage converters, and an unregulated voltage bus coupled to at least one of the unregulated voltage converters. The power supply includes a voltage regulator coupled to the unregulated voltage bus and producing a regulated voltage across its output terminals. The output terminals of the voltage regulator are connected in parallel to the output terminals of at least one of the unregulated voltage converters. This can produce a regulated output voltage across a pair of power supply output terminals.
