21-Watt Universal AC LED Driver with Accurate Average-Mode Constant Current Control

https://www.electronics-lab.com/project/21-watt-universal-ac-led-driver-with-accurate-average-mode-constant-current-control/

The project presented here is an average current mode control LED driver operating in a constant off-time mode. The project consists of a bridge rectifier followed by a buck converter operating with a fixed off-time of 20µs. The circuit provides accuracy, and line and load regulation of the LED current. The output LED current accuracy […]
