Abstract
A system and method providing output voltage control in a power supply circuit. Various aspects of the present invention may comprise at least a first module adapted to receive an input DC voltage and at least one voltage control signal and output an output DC voltage that is a function of the input DC voltage and the voltage control signal. At least a second module may be adapted to receive a feedback signal representative of the output DC voltage and output the at least one voltage control signal as a function of at least the feedback signal. The second module may, for example, be a digital module adapted to generate the at least one voltage control signal utilizing digital active components. The second module may also, for example, utilize transistors and/or passive components controlled by the digital active components to generate the at least one voltage control signal.
