Abstract
A tracking regulator for a plurality of light emitting diode (LED) loads is provided. The tracking regulator includes a power supply and a control circuit coupled to the power supply. The power supply provides a power signal to each of the LED loads according to a control signal, wherein each of the LED loads provides an output signal according to the power signal. The control circuit detects the output signals from the LED loads to generate the control signal, so as to control the power supply to adjust the power signal.
Claims18
A tracking regulator for a plurality of light emitting diode (LED) loads, comprising:
- a power supply, providing a power signal to each of the LED loads according to a first control signal, wherein each of the LED loads provides an output signal according to the power signal;
- and
- a first control circuit coupled to the power supply, detecting the output signals from the LED loads to generate the first control signal, so as to control the power supply to adjust the power signal.
