Linear low-voltage-drop LED driver IC
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.
- Supply voltage from 6 to 42V
- Controls up to 100mA LED current
- Typ. 135mV saturation voltage at 50mA
- LED current precision ±5%
- Smart over temperature protection
