Abstract

Disclosed herein are a switched-mode power supply and a method therefor. The switched-mode power supply has an input and an output and includes an input voltage conditioner, a transformer, a switching control circuit, an output voltage conditioner and a feedback voltage conditioner, which are operatively coupled. In addition, the switched mode power supply includes a start-up circuit operatively coupled to the input voltage conditioner and the switching control circuit, wherein the start-up circuit is configured to substantially provide electrical power to the switching control circuit during start-up and until the feedback voltage conditioner provides a predetermined voltage to the switching control circuit.
