BCR430U Low Voltage Drop LED Driver IC Feature list Supply voltage from 6 V to 42 V Controls up to 100 mA LED current Typ. 135 mV saturation voltage at 50 mA LED current precision 5 % at 95 mA Smart over temperature protection function Advantages with respect to discrete solutions Low BOM count Lower assembly cost Smaller form factor Higher reliability due to less parts and soldering joints Potential Applications LED strips LED displays and channel letters Architectural and landscape lighting Retail lighting Product Validation Qualified for industrial applications according to the relevant tests of JEDEC47/20/22 Product Name Package BCR430U PG-SOT23-6 Description BCR430U 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 100 mA connecting a high ohmic resistor Rset to pin RS. The maximum voltage drop at the integrated LED driver stage is 200 mV at 50 mA improving the overall system efficienc y and providing extra voltage headroom to compensate for tolerances of LED forward voltage or supply voltage. The smart over temperature protection function reduces the LED current when junction temperature of BCR430U is very high.
