A controller generates a gate pulse signal having a duty ratio adjusted such that the voltage drop at the detection resistor matches a predetermined reference voltage. Furthermore, the controller receives a dimming control signal which indicates the duty ratio of the burst dimming operation, and generates a corresponding burst dimming pulse. According to the gate pulse signal, the first driver drives an output circuit configured to generate a driving voltage. A second driver switches a path of a driving current between connection and disconnection according to the burst dimming pulse. A duty ratio detection unit controls the frequency of the gate pulse signal according to the duty ratio indicated by the dimming control signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Driving circuit for light-emitting element with burst dimming control","description":"A detection resistor is arranged on a path of an LED string.
