Linear Current Source LED Driver with Dimmer Input

The compact module shown here is a linear current source for LED driver and it’s ideal for automotive LED lighting applications. The project is built using a TLD1211 chip from Infineon. The board provides supply to LEDs under the severe condition of automotive applications resulting in constant brightness and extended LED lifetime. The project is capable to drive high current, high brightness LEDs. The circuit features overload, short circuit, over-voltage, and over-temperature protections. It also has the option to control the LED brightness control by an external PWM signal.
