摘要： The present invention relates to circuits and methods for controlling one or more LED strings. The circuit comprises a programmable controller coupled to one or more detectors, wherein the one or more detectors are configured to detect one or more measurable parameters of one or more LEDs or LED drivers. The controller is configured to receive information from the one or more detectors related to the one or more measurable parameters and use that information to determine the desired drive voltage for the LED strings. The controller is associated with a power supply having power factor correction (PFC) capability. The controller provides the power supply with a control signal indicative of the desired drive voltage for one or more LED strings. The power supply also receives ac voltage and current waveforms as inputs and performs power factor correction and rectified waveforms related to the ac waveforms. The power supply generates the desired drive voltage based on the control signal.

摘要： A method for controlling a step down regulator includes (a) generating a first feedback signal as a function of the voltage at the output node; (b) generating a second feedback signal as a function of the voltage at the input node; (c) maintaining the on-time of the low-side switch at a fixed duration; and (d) varying the on-time of the high-side switch to be proportional to the first feedback signal and inversely proportional to the second feedback signal so that the switching frequency of the high and low side switches is approximately constant.
