Abstract:
A parameter setting and circuit protecting method applied in a power converter are disclosed. An input voltage of the power converter is detected to generate a first detecting signal related to the input voltage. The first detecting signal will be thence compared with a threshold so as to generate a protecting signal for protecting the power converter. When a parameter setting signal is triggered, a current is provided so as to make the first detecting signal to generate a variation, thereby setting a parameter in accordance with the variation.
