... Medical lighting Automotive applications like CHMSL and rear combination lights General Description The BCR402U is a cost efficient LED driver to drive low power LED’s. The advantages towards resistor biasing are: homogenous light output despite varying forward voltages in different LED strings homogenous light output of LED’s despite voltage drop across long supply lines homogenous light output independent from supply voltage variations longer lifetime of the LED’ ...

... Application hints BCR402U serves as an easy to use constant current source for LEDs. In stand alone application an external resistor can be connected to adjust the current from mA. Rext can be determined by using the diagram 'Output current versus external resistor refering to diagram 'Reference voltage versus output current'. Look for your desired output current on the x axis and read out the corresponding Vdrop ...
