Infineon BCR402WH6327: High-Performance Constant Current LED Driver

The Infineon BCR402WH6327 is a linear constant current LED driver designed to deliver exceptional stability and efficiency in a wide range of lighting applications. As a member of Infineon’s growing portfolio of LED driver ICs, this device stands out for its simplicity, reliability, and compact form factor, making it an ideal choice for both consumer and industrial lighting systems.

One of the key advantages of the BCR402WH6327 is its ability to maintain a consistent current output despite fluctuations in supply voltage or forward voltage variations of the LEDs. This ensures uniform brightness across multiple LEDs and significantly extends their operational lifespan by preventing current-induced thermal stress. The device supports a maximum output current of 70 mA, which can be easily adjusted using an external resistor, offering designers valuable flexibility.

Housed in a small SOT-143 package, the BCR402WH6327 is optimized for space-constrained PCB designs. Its linear regulation architecture eliminates the need for bulky inductors or electrolytic capacitors, reducing both system cost and board space. Additionally, the IC operates with very low electromagnetic interference (EMI), which simplifies compliance with electromagnetic compatibility (EMC) standards.

The driver incorporates built-in protection features such as over-temperature control and reverse polarity protection, enhancing system robustness in demanding environments. It is particularly well-suited for low- to mid-power LED applications, including decorative lighting, signage, retail display lighting, and automotive interior lights.
