Abstract:
A control circuit 10 according to the present invention transits to a first current limiter mode when an output current of a DC-DC converter circuit reaches an upper limit current or greater in a normal mode; transits to the normal mode when the output current falls below the upper limit current in the first current limiter mode; transits to a second current limiter mode when a first predetermined period elapses without a transition to the normal mode in the first current limiter mode; and transits to the normal mode when a second predetermined period elapses in the second current limiter mode.
