Abstract/Summary
In this work, we implemented the idea of current foldback protection onto a buck converter. Current foldback protection essentially helps reduce the power dissipation which may be caused by a short circuit or overload scenario. To achieve the goal of this project, we used a combination of comparators, operational amplifiers and MOSFETs to create a current foldback sub controller. This controller would then serve as a feedback device between the output of the converter and the main controller to detect if a fault condition has occurred. Following the design, we performed simulation of the current foldback controller using PSpice and then physically constructed it on a breadboard. For the Buck converter part of the project, we utilized Texas Instrument’s LM76002 Evaluation Module. Both results from simulation and hardware testing prove that the current foldback controller design operates and meets the desired functionalities of the project as a whole.
