Infineon's BCR431U is a linear LED driver IC in a small SOT23-6 package regulating the LED current in standalone operation without any external power transistor. It is suitable for driving currents up to 37mA and the IC supply voltage ranges from 6V up to 42V. The LED current level can be adjusted by connecting a high-ohmic resistor RSET to pin RS. The voltage drop at the integrated LED driver stage is 200 mV max. at 37 mA improving the overall system efficiency and providing extra voltage headroom to compensate for tolerances of LED forward voltage and supply voltage.
