PROBLEM TO BE SOLVED: To prevent a rush current prevention circuit 208 from operating while a load side is short-circuited to break down an FET Tr301 inside the circuit.SOLUTION: A switching circuit K400 is configured such that a resistor R401 is connected in parallel to an FET Tr301 and the gate of the FET Tr301 is not turned on until a voltage of a load-side power source Vo exceeds a predetermined voltage. |
