Abstract
A regulator for converting a DC input voltage into a DC output voltage includes: a control module generating a predetermined regulated voltage associated with the DC output voltage, and further generating a control signal based on a feedback voltage associated with the DC output voltage; a switching module outputting, in response to the control signal, one of the reference voltage and the regulated voltage as a switching voltage; and a conversion module generating the DC output voltage and the feedback voltage based on the DC input voltage, a reference voltage output from the reference voltage generation module and the switching voltage.
