Abstract
System and method for dimming control. The system includes a system controller including a first controller terminal and a second controller terminal, a transistor including a first transistor terminal, a second transistor terminal and a third transistor terminal, and a resistor including a first resistor terminal and a second resistor terminal. The system controller is configured to generate a first signal at the first controller terminal based on an input signal and to generate a second signal at the second controller terminal based on the first signal. The first transistor terminal is coupled to the second controller terminal. The first resistor terminal is coupled to the second transistor terminal. The second resistor terminal is coupled to the third transistor terminal. The transistor is configured to receive the second signal at the first transistor terminal and to change between two conditions in response to the second signal.
