Abstract
A regulated power apparatus is provided. The apparatus includes an input power converting circuit configured for receiving a rectified voltage and for generating an increased voltage. An intermediate power regulating circuit generates a regulated voltage that has a lower voltage than a minimum output voltage of the input power converting circuit. The intermediate power regulating circuit is coupled to receive the increased voltage. An output power converting circuit is coupled with the intermediate power regulating circuit. The output power converting circuit receives the regulated voltage and generates an output voltage that is lower than the regulated voltage. The output power converting circuit comprises a buck converter configured to operate at a fixed duty cycle. A regulation circuit is coupled with the intermediate power regulating circuit and coupled with the output power converting circuit.
