Abstract
A current control circuit comprises a current proportional circuit having two terminals, the current of one terminal being a proportional relationship with the current of the other terminal. An output terminal coupled with the current proportional circuit and a load through which a controlled current flows, and a constant current source. A steering circuit to which a switching signal is applied, is provided between the two terminals of the current proportional circuit and the constant current source, in order to couple the constant current source to one of the two terminals in response to the switching signal.
