Abstract
A power supply converter is disclosed. An apparatus according to aspects of the present invention includes a power supply converter having an energy transfer element coupled between a power converter input and first and second power converter outputs. A switch is coupled between the power converter input and the energy transfer element. A control circuit is coupled to the switch to control switching of the switch to generate a first output voltage at the first power converter output and a second output voltage at the second power converter output. A sum of the first and the second output voltages is regulated in response to a first voltage reference. The second output voltage is regulated in response to a second voltage reference. A current in the energy transfer element is coupled to be increased when a voltage across the energy transfer element is a difference between an input voltage at the power converter input and the first output voltage. The current in the energy transfer element is coupled to be decreased when the voltage across the energy transfer element is the sum of the first and second output voltages.
