Techniques are disclosed to control a power converter with multiple output
voltages. One example regulated power converter includes a 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 such that switching of
the switch causes a first output voltage to be generated at the first
power converter output and a second output voltage to be generated at the
second power converter output. A current in the energy transfer element
is coupled to increase 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 decrease when the voltage across the energy transfer element
is a sum of the first and second output voltages.
