LED driver

close

The LED driver supplies constant current to the LEDs and has circuit and LED fault detection capabilities. For high current LEDs, switching LED drivers are used in order to improve efficiency and mitigate thermal dissipation. Linear LED drivers are used for low current LEDs in order to simplify system design.
