1. A regulator for converting a DC input voltage into a DC output voltage, said regulator comprising:
a reference voltage generation module used to receive the DC input voltage, and operable to generate a first reference voltage output and a second reference voltage based on the DC input voltage; a control module operable to generate a predetermined regulated voltage associated with the DC output voltage, and to further generate a control signal based on a feedback voltage associated with the DC output voltage; a switching module coupled to said reference voltage generation module and said control module for receiving the second reference voltage from said reference voltage generation module, and the predetermined regulated voltage and the control signal from said control module, said switching module being operable to output, in response to the control signal, one of the second reference voltage and the predetermined regulated voltage to serve as a switching voltage; and a conversion module used to receive the DC input voltage, and coupled to said reference voltage generation module, said control module and said switching module, said conversion module further receiving the first reference voltage output from said reference voltage generation module, and the switching voltage from said switching module, said conversion module being operable to generate the DC output voltage and the feedback voltage based on the DC input voltage, the first reference voltage output and the switching voltage. |
