BCR430U LED Driver Evaluation Board Infineon BCR430U LED Driver Evaluation Board is used for linear and low-voltage-drop LED driver designs based on the Infineon BCR430U controller IC. The eval board offers a 24V/100mA (max. LED current) solution. Infineon BCR430U is a linear LED controller IC in a small PG-SOT23-6-1 package regulating the LED current in standalone operation without any external power transistor.
