Abstract
A voltage converting circuit includes an input terminal, an output terminal, a main circuit a feedback terminal, a testing unit, and a detection unit. The main circuit is coupled between the input terminal and the output terminal to convert a first voltage input from the input terminal into a second voltage and output the second voltage via the output terminal. The feedback terminal is coupled to the output terminal and the testing unit is coupled to the feedback terminal to output a testing current to the feedback terminal to change a third voltage of the feedback terminal. The detection unit is coupled between the feedback terminal and the main circuit. The detection unit detects a change to the third voltage feedback from the feedback terminal to enable or disable the main circuit according to the change to the third voltage.
