A method is disclosed for converting DC power from a first voltage level on an input to a different voltage level on an output for delivery to a load. The method includes switching current in a switching operation from the input to the output through an inductive element and measuring the voltage/current parameters on the input and output. A control algorithm is then utilized to determine control parameters necessary to make a control move to effect the switching operation, the control algorithm utilizing as inputs the measured voltage/current parameters. A digital control system controls the switching operation, which digital control system is operable to be controlled by the control algorithm. Configuration data is received on a serial data bus for configuring the control algorithm. Thereafter, the operation of the control algorithm is modified in response to receiving the configuration information.
