Abstract:
The invention provides a constant current control device and a television including the constant current control device. The constant current control device includes a constant current control module and a switched-mode power supply module used for providing a stable voltage for a load. The constant current control module includes a constant current source unit used for providing a reference current, a constant current control unit used for keeping a current flowing through the load constant as the reference current, and a feedback unit used for keeping the voltage of the constant current control unit constant. The present invention, with a simple circuit structure, implements the objective of precisely controlling a current passing through a load.
