Abstract
A power supply apparatus converts an input voltage () into a first () and a second output voltage (). The first () and the second output voltage () are put into and/or out of operation sequentially. The power supply apparatus comprises a first converter unit () which converts the input voltage () into the first output voltage (), and a second converter unit () for providing the second output voltage (). The second converter unit input () is coupled to the first converter unit output (). The second converter unit () can only start and provide an output voltage after the first converter unit () has started. During power-down, a sequence is created in which the second converter unit remains operational until any capacitance coupled to the first converter unit output has been discharged.
