Abstract
The present disclosure provides a light-emitting diode (LED) driver circuit and an electronic device. The LED driver circuit includes a rectifier-filter circuit configured to convert an alternating voltage into a direct voltage; a valley-filling circuit connected to the rectifier-filter circuit and configured to adjust a current waveform from the rectifier-filter circuit; a ringing choke converter (RCC) circuit connected to the valley-filling circuit and configured to control a direct current (DC) output; and a DC output unit connected to the RCC circuit and configured to rectify and filter an output signal from the RCC circuit so as to drive an LED load.
