The power converter circuit is configured to provide an output current to an LED load coupled thereto. The feedback circuit is configured to generate an error signal which is fed back to the power converter circuit for maintaining the power converter circuit in a constant current output state. The buffer circuit is coupled to the LED load and configured for quick turn off of the LED load and for temporary storage of power. The energy recovery circuit is configured to reuse the power stored in the buffer circuit before relying on an external power source to power the controller and the feedback circuit. The controller is configured to control at least one aspect of each of the circuits of the LED driver."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light modulating control method for dimming analog constant current LED driver","description":"An LED driver for light modulation control includes a power converter circuit, a feedback circuit, a buffer circuit, an energy recovery circuit, and a controller.
