Diodes releases BCR430UW6 LED driver with 115mV dropout voltage

This combination makes the BCR430UW6 suitable for applications that require multiple LEDs to operate together, such as signage illumination and architectural lighting for commercial and retail installations.

The “ultra-low” dropout voltage and operating current of 285μA provide a greater level of system efficiency and scope to drive more LEDs per string reliably, the firm claims.

The device requires no external power transistors or capacitors, reducing the overall BoM.

Its long-term reliability is improved through tolerance to overvoltage levels resulting from faults in the LEDs or supply transients. Additionally, integrated thermal protection limits the output current in the event of high operating temperatures.

With an adjustable output current level between 5mA and 100mA, the device can be used to drive various LED configurations. The output is stable to ±5% across temperature variations and supply voltage fluctuations. This stability delivers a uniform output lighting level under all operating conditions, Diodes says.

Other features touted by the manufacturer 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.
