ABSTRACT:
Techniques are disclosed to regulate an output current through a load coupled to a power converter using a current source coupled to the load. For instance, one power converter according to the teachings of the present invention includes an energy transfer element coupled between an input of the power converter and an output of the power converter. The power converter also includes a controller circuit coupled to the energy transfer element and the input of the power converter to regulate the output of the power converter. A current source circuit is also included and is coupled to the output of the power converter to limit an output current of the power converter to below a threshold value.
