Patent attributes
A load control device for an electrical load may operate in a normal mode and a burst mode to adjust the amount of power delivered to the electrical load. The load control device may comprise a control circuit that operates in the normal mode to regulate an average magnitude of a load current conducted through the load between a maximum rated current and a minimum rated current. During the normal mode, the control circuit may control the operating period of a load regulation circuit between a high-end operating period and a low-end operating period. The control circuit may operate in the burst mode to regulate the average magnitude of the load current below the minimum rated current. During the burst mode, the control circuit may adjust the low-end operating period to be less than or equal to a minimum on time of the load regulation circuit.
