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 20 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. Potential applications include, LED strips, architectural LED lighting, LED displays and channel letters, emergency lighting, retail lighting, and white good lighting.

The TLE4309 is an integrated adjustable constant current source for driving loads up to 500 mA. The output current level can be adjusted with an external shunt resistor. Supplying high power LEDs with the TLE4309 ensures constant brightness independent from supply voltage or LED forward voltage spread. Therefore, LED lifetime is extended by protecting from overcurrent and overtemperature. The TLE4309G is provided in the surface mounted PG-TO-263 package with excellent thermal resistance.
