ABSTRACT:
The overcurrent protection circuit has a first output voltage detection circuit which compares an output voltage with a first reference value in a first timing after the output circuit starts outputting the output voltage, a second output voltage detection circuit which compares the output voltage with a second reference value in a second timing, and an output control circuit which stops the output from the output circuit according to the output from the first or second output voltage detection circuit.
