Title: Constant current circuit
Inventor: SHIOKAWA KATSUMI
IPC: H01L27/06
Filed: 2001-01-29
Abstract: PROBLEM TO BE SOLVED: To provide a constant current circuit that can turn on an LED with a luminance always according to a setting even at a high-speed switching independently of the quantity of an output current. SOLUTION: When an output transistor(TR) is conductive, after a constant current flowing to a load is set to an optional value, and when the output TR is switched to supply a prescribed current to the load and the output TR is conductive, an excessive base current is separately supplied to the base of the output TR. Thus, even when a switching control signal is small, when the switching control signal reaches a high level, the output TR is immediately conductive to be transited to a constant current operation so as to supply the power according to the setting can be supplied to the load LED. Thus, even at a high-speed switching independently of the quantity of the output current, the LED can turn on with the luminance prescribed at all times.
