Infineon provides an online tool for the BCR4xx LED driver family, which guides you, based on the inputs, to the proper driver for your General and Industrial lighting LED application without the need to take a deep dive into technical detals.
First, the basic parameters for the LED circuit need to be set:

• - Supply voltage
• - Forward voltage and current of the LEDs
• - The number of LEDs in series and/or parallel
• - Additional configuration details like thermal protection or Automotive qualified parts only

The tool will then recommend a LED driver and draw an application schematic, where you can interactively modify the parameters. A simulation that follows this step shows the effects of the changes made in diagrams. In the results section you find a summary of the application schematic, the simulation data and the bill of material. You can save the specific parameters and the progress in the tool at any time for later evaluation or modification. With this great support tool you can quickly evaluate a suitable LED driver for your desired application.
