Abstract
System and method for dimming control. The system includes a system controller, a transistor, and a resistor. The system controller includes a first controller terminal and a second controller terminal. The transistor includes a first transistor terminal, a second transistor terminal and a third transistor terminal. The resistor including a first resistor terminal and a second resistor terminal. The first transistor terminal is coupled, directly or indirectly, 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 system controller is configured to receive an input signal at the first controller terminal and to generate an output signal at the second controller terminal. The transistor is configured to receive the output signal at the first transistor terminal and to change between a first condition and a second condition.
