Product Name Package Marking

BCR430U PG-SOT23-6-1 43

Description

BCR430U is a linear LED controller IC in a small PG-SOT23-6-1 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 voltage drop at

the integrated LED driver stage is less than 200 mV at 50 mA improving the overall system eiciency 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.
