Long term reliability and longevity of LEDs are key. BCR430U is the best choice when you need to drive low power LED strings and strips supplied by a DC voltage source and at the same time requesting more flexibility in voltage headroom.
BCR430U is a linear LED controller IC in a small SOT23-6 package regulating the LED current in standalone operation without the need of any external power transistor. It is suitable for driving currents from 5 to 100mA and the IC supply voltage range is from 6V up to 42V. The LED current level can be adjusted connecting a high ohmic resistor Rset to pin RS.
