ABSTRACT:
The overcurrent protection circuit for a dc-to-dc converter which inputs an input voltage through a power input line, converts the voltage into another voltage to output as an output voltage to a load through a power output line. The overcurrent protection circuit outputs a first connection signal for a predetermined period from the time the input voltage is turned on; detects an overcurrent caused in the load and outputs a second connection signal from the time tile input voltage is turned on until the overcurrent is detected; and closes the power input line while receiving at least one of the first and second connection signals.
