Abstract: Methods, systems, and devices are described for providing fault monitoring for light emitting diode (LED) circuits. Embodiments receive an indication from a fault control module that a fault has occurred in a portion of an LED module (e.g., a series string of LEDs). The fault may represent an open fault or a closed fault condition. In some embodiments, a monitoring module receives the fault indication and generates a further representation that the fault has occurred (e.g., for use by external components or systems). In other embodiments, the monitoring module in configured to further indicate which in the LED module has failed, and/or in what fault condition (e.g., open or closed).

Abstract: Methods, systems, and devices are described for an adjustment module that interacts with a parameter detection module to provide a threshold value for initiating switching of a switching module in a cyclical electronic system. Aspects of the present disclosure provide a switching module used in conjunction with an inductor that is coupled with the switching module. The threshold voltage for switching the switching module may be adjusted to provide switching at substantially zero volts while maintaining sufficient energy in the inductor to drive the voltage at a switching element in the switching module to zero volts. Such auto-adjustment circuits may allow for enhanced efficiency in cyclical electronic systems. The output of an up/down counter may be used to set another parameter that effects the performance of the cyclical electronic system in order to enhance the performance of the cyclical electronic system.
