Diodes Inc’s Latest Linear LED Driver Extends Lighting Strip Capacity

January 8, 2020 Alix Paultre

Diodes Incorporated released the BCR430UW6 linear LED driver with ultra-low dropout voltage and constant current regulation between 5mA and 100mA, allowing more LEDs to be driven from a low supply voltage. With a dropout voltage of 115mV and operating current of 285μA, the device requires no external power transistors or capacitors, reducing the overall BoM cost and increasing system stability. Integrated thermal protection limits the output current in the event of high operating temperatures, avoiding operational failure and maximizing the working lifetime of the system.

The adjustable output current is between 5mA and 100mA, and is highly stable, held at ±5% across temperature variations and supply voltage fluctuations, to deliver a uniform output lighting level under all operating conditions. Other features include PWM-based dimming, an operating voltage range of 5V to 42V, and support for parallel operation to further increase the regulated output current. The BCR430UW6 is provided in a SOT26 package and priced at $0.10 in 5000 piece quantities.
