This improves overall efficiency and provides the voltage headroom required to compensate for LED forward voltage tolerances and variances in the supply voltage. The part does not require any external power transistor and additional LEDs can be added to lighting designs without changing the supply voltage. Typical applications for the BCR430U include LED strips, architectural LED lighting, LED displays as well as retail, appliance and emergency lighting.

Delivered in a SOT-23-6 package, the LED driver current ranges between 5mA and 100mA, and can be easily adjusted via high ohmic resistor on a dedicated pin. The supply voltage ranges between 6V and 42V. For safe and reliable operation and to extend the LED lifetime, a smart over-temperature controlling circuit reduces the LED current when the junction temperature is very high.
