Abstract: A power converter that properly copes with the wiring defects on a feedback path is shown. According to a control signal, a power driver couples an input voltage to an energy storage element to provide an output voltage that is down-converted from the input voltage. The output voltage is further converted into a feedback voltage by a feedback circuit, and is entered to an error amplifier with a reference voltage for generation of an amplified error. A control signal generator generates the control signal of the power driver according to the amplified error. The power converter specifically has a comparator, which is enabled in a soft-start stage till the output voltage reaches a stable status. The comparator compares the amplified error with a critical value. When the amplified error exceeds the critical value, the input voltage is disconnected from the energy storage element.
