Abstract:
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.

Claim (Index 1):
A circuit for controlling an intensity of a light-emitting diode (LED) light source, the circuit comprising:\n an LED drive circuit configured to control a magnitude of a load current conducted through the LED light source to control the intensity of the LED light source; a current sense circuit configured to provide a load current feedback signal that indicates the magnitude of the load current; and a control circuit configured to generate at least one drive signal for controlling the LED drive circuit to adjust the magnitude of the load current, the at least one drive signal characterized by an operating period and a duty cycle; wherein the control circuit is further configured to:\n operate in a first state and a second state on a periodic basis; \n control the LED drive circuit in the first state during a first time period in which the control circuit adjusts an on time of the at least one drive signal in response to the load current feedback signal to regulate a peak magnitude of the load current towards a target current; \n control the LED drive circuit in the second state during a second time period in which the control circuit ceases adjustment of the on time of the at least one drive signal in response to the load current feedback signal; \n adjust an average magnitude of the load current by adjusting respective lengths of the first and second time periods; and \n adjust the operating period of the at least one drive signal to a low-end operating period by adjusting the on time of the at least one drive signal to a value less than or equal to a minimum on time while holding the duty cycle of the at least one drive signal constant.
