A multi-stage driver system includes a switched mode power circuit for providing a direct current (DC) power signal to an electrical load and a control block. Control block includes interfaces coupled to receive at least one real-time input signal from a high voltage region or a low voltage region of the switched mode power circuit and to provide at least one control signal to the high voltage region or the low voltage region. Control block configures the switched mode power circuit to provide the DC power signal having at least one power parameter within a tolerance of a power configuration setting value of the electrical load. Control block responds to the at least one real-time input signal from the high voltage region or the low voltage region to adjust operation of the high voltage region or the low voltage region via the at least one control signal.
