1. A load control device for controlling an amount of power delivered to an electrical load, the load control device comprising:a load regulation circuit configured to control a magnitude of a load current conducted through the electrical load to control the amount of power delivered to the electrical load;
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 load regulation circuit to adjust an average magnitude of the load current;
wherein the control circuit is configured to operate in an active state during an active time period to adjust an operational characteristic of the at least one drive signal in response to the load current feedback signal in order to regulate a peak magnitude of the load current to a target current, the control circuit further configured to operate in an inactive state during an inactive time period to stop generating the at least one drive signal in response to the load current feedback signal, the control circuit configured to operate in the active state and the inactive state on a periodic basis over a plurality of burst periods, each of the burst periods including the active time period and the inactive time period; and
wherein the control circuit is configured to adjust the average magnitude of the load current by adjusting a length of the inactive time period while holding a length of the active time period constant in at least some of the burst periods.
