Infineon BCR431UXTSA1 LED Driver IC, 6 → 42 V 60μA

The Infineon low voltage drop LED driver IC is a linear LED driver IC in a small PG-SOT23-6 package regulating the LED current in standalone operation without any external power transistor. The IC supply voltage range is from 6 V up to 42 V. The LED current level can be adjusted up to 36.5 mA connecting a high ohmic resistor Rset to pin RS. The maximum voltage drop at the integrated LED driver stage is 200 mV at 32.8 mA improving the overall system efficiency and providing extra voltage headroom to compensate for tolerances of LED forward voltage or supply voltage.
