Abstract
There is provided a load driving apparatus including: a power converter circuit configured to convert electric power into direct current power; an output electric current detecting circuit configured to detect an output current flowing in the load; and a control circuit section configured to switch ON/OFF-operations of the load depending on an operation instruction information, to perform constant current control during a period of the ON-operation of the load, to output a first pulse signal to the power converter circuit when starting the constant current control, ON-duty of the first pulse signal being substantially same as that during a period of a most recent operation of the load performed immediately before, to perform constant voltage control during a period of the OFF-operation of the load based on an output voltage applied to the load, and to output a second pulse signal to the power converter circuit.
