Due to the growing demand for small LED lighting equipment with high efficiency and ultra-low EMI, Diodes has expanded its popular line of BCR420U and BCR421U linear LED drivers to include the BCR420UFD and BCR421UFD units in the ultra-low DFN2020 package. 12V and 24V LED edge lighting applications. The main benefits of LED lighting are longer life and higher efficiency, and the demand for more variable and less invasive solutions continues to increase, including luminaires that are illuminated by the edges rather than vertically. In response to this demand, manufacturers are looking for solutions that support a thinner overall look. With a package height of only 0.6mm, the DFN2020 is the perfect choice for edge lighting. The new device, like the BCR4xxU family, offers an adjustable constant current between 10mA and 200mA (BCR420UFD) or 350mA (BCR421UFD) ±10% tolerance; the BCR421UFD can be controlled with PWM signals up to 25kHz and 1% duty cycle. LED dimming function. Both devices feature a negative temperature coefficient that reduces LED driver current when internal temperature rises, thereby protecting and extending LED life. In addition, the linear topology is based on an NPN emitter follower with an emitter resistor, which represents a device with little EMI, making it ideal for sensitive applications such as medical lighting. The device's wide operating voltage range (between 1.4V and 40V) and a total power consumption of up to 1.7W are suitable for driving longer LED strips while still providing adequate protection against 24V systems. The transient in. The device is designed as an integrated solution that integrates transistors, diodes and resistors in a package that is only 0.6mm high. This thickness is much lower than the SOT26 package, allowing engineers, architects, and lighting designers to develop lower-profile LED devices for a wider range of applications. Edge lighting is currently specified for emergency, atmospheric or decorative lighting, but is equally applicable to medical, industrial and commercial environments. The BCR420UFD and BCR421UFD linear constant current regulators for LED lighting are currently available in volume production.
