Ultra-Low Dropout Linear LED Driver from Diodes Incorporated Extends Lighting Strips

Sponsored by Businesswire

Diodes Incorporated (Nasdaq: DIOD) today announced the BCR430UW6
linear LED driver with ultra-low dropout voltage and constant current
regulation between 5mA and 100mA. This combination allows more LEDs to
be driven from a low supply voltage, making 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 of 115mV and low operating current of just
285μA provides a greater level of system efficiency and scope to drive
more LEDs per string reliably. These factors are particularly important
in applications where the characteristics of the lighting are essential
to the user experience, such as signage and architectural illumination.

The device requires no external power transistors or capacitors,
reducing the overall BoM cost and increasing system stability. Long-term
reliability is also improved through the robust design, which is
tolerant to overvoltage levels resulting from faults in the LEDs or
supply transients. Integrated thermal protection limits the output
current in the event of high operating temperatures, avoiding
operational failure and maximizing the working lifetime of the LEDs.

With an adjustable output current level between 5mA and 100mA, the
BCR430UW6 can provide greater flexibility, allowing a single design to
be used to drive various LED configurations. The output is highly
stable, held at ±5% across temperature variations and supply voltage
fluctuations. This stability delivers a uniform output lighting level
under all operating conditions.

Other advanced 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.
