    Abstract: A load control device (100) for controlling the amount of power delivered to an electrical load is able to operate in a burst mode (T BURST ) to adjust the amount of power delivered to the electrical load to low levels. The load control device (100) comprises a control circuit (150) that operates in a normal mode to regulate an average magnitude (I AVE ) of a load current (I LOAD ) conducted through the load to a target load current (I TRGT ) that ranges from a maximum (I MAX ) rated current to a minimum rated current (I MIN ). The control circuit (150) operates in the burst mode (T BURST ) to regulate the average magnitude (I AVE ) of the load current (I LOAD ) below the minimum rated current (I MIN ). During the burst mode (T BURST ), the control circuit (150) regulates a peak magnitude of the load current (I LOAD ) to the minimum rated current (I MIN ) during a first time period (T ACTIVE ), and stops regulating the load current (I LOAD ) during a second time period (T INACTIVE) , such that the average magnitude (I AVE ) of the load current (I LOAD ) is below the minimum rated current (I MIN ).

    Abstract: Provided herein are examples of a remote control device that provides a retrofit solution for an existing switched control system. The remote control device may comprise a control circuit, a rotatable portion, a magnetic ring coupled to the rotatable portion, and first and second Hall-effect sensor circuits configured to generate respective first and second sensor control signals in response to magnetic fields generated by the magnetic elements. The control circuit may operate in a normal mode when the rotatable portion is being rotated, and in a reduced-power mode when the rotatable portion is not being rotated. The control circuit may disable the second Hall-effect sensor circuit in the reduced-power mode. The control circuit may detect movement of the rotatable portion in response to the first sensor control signal in the reduced-power mode and enable the second Hall-effect sensor circuit in response to detecting movement of the rotatable portion.
