Abstract
The present invention provides a power control circuit and a dimming control circuit, the circuit includes: a power supply voltage stabilizing circuit, a power adjusting circuit, and an output circuit; the power supply voltage stabilizing circuit is configured to convert a power supply voltage of the voltage source into an input voltage of a preset voltage value, and transmit the input voltage to the power adjusting circuit; the power adjusting circuit is configured to convert the input voltage into an output voltage of a preset power by adjusting a voltage division ratio of the voltage division resistor; the output circuit is configured to operationally amplify and follow the output voltage, and output a brightness control voltage. Using the embodiments of the present invention, power adjustment of the output voltage can be achieved, thereby satisfying the power match for different dimming interfaces.
