Lighting driver for driving light-emitting component at high speed
Abstract:
A lighting driver for driving a light-emitting component at a high speed is provided. A control terminal of a second transistor is connected to a control terminal and a first terminal of a first transistor. Input terminals of an operational amplifier are connected to the first terminal of the first transistor and first terminals of first and second switches. Control terminals of third and fourth transistors are connected to an output terminal of the operational amplifier. Second terminals of the first switch and the fourth transistor are connected to a first terminal of the second transistor. A second terminal of the second switch and a current source are connected to a second terminal of the third transistor. A first terminal of the fourth transistor is connected to the light-emitting component. A control circuit is connected to the current source, and control terminals of the first and second switches.
