Infineon Technologies BCR430U Low Drop Voltage LED Driver IC
Infineon BCR430U Low Drop Voltage LED Driver IC can regulate LED current in standalone operations without an external power transistor. The BCR430U is housed in a small PG-SOT23-6-1 package with an IC supply voltage range from 6V up to 42V. The LED current level can be adjusted up to 100mA connecting a high ohmic resistor Rset to pin RS.
The voltage drop at the integrated LED driver stage is less than 200mV at 50mA. This improves system efficiency while providing extra voltage headroom to compensate for LED forward voltage or supply voltage tolerances. The smart over-temperature protection function reduces the LED current when junction temperature of BCR430U is very high.
