摘要
Controller of LED lighting to control the maximum voltage of LEDs and the maximum voltage across current sources is provided. A voltage-feedback circuit is coupled to the LEDs to sense a voltage-feedback signal for generating a voltage loop signal. Current sources are coupled to the LEDs to control the LED currents. A detection circuit senses the voltages of the current sources for generating a clamp signal in response to a maximum voltage of the current sources. Furthermore, a buffer circuit generates a feedback signal in accordance with the voltage loop signal and the clamp signal. The feedback signal controls the maximum voltage of the LEDs and the maximum voltage across the current sources.
