From the project
KiCad-based 24V constant-current LED driver using PT4115 with LM393-based automatic dimming control and a single-layer PCB design.
A compact 24V constant-current LED driver designed around the PT4115 switching LED driver IC, with an LM393-based automatic dimming control stage.
The project is designed as a practical, low-cost hardware solution for driving an LED load at approximately 3.5 W, while providing automatic switching between normal and dimming modes without requiring an external microcontroller.
