The BCR 401R E6327 is a LED Driver with higher output current accuracy. The BCR401R can be operated at higher supply voltages by putting LEDs between the power supply VS and the power supply pin of the LED driver. The BCR401R is a perfect fit for numerous low power LED applications by combining small form factor. This LED driver offers several advantages to resistors like significantly higher current control at very low voltage drop ensuring high lifetime of LEDs. It features longer lifetime of the LEDs due to reduced output current at higher temperatures (negative thermal coefficient). Dimming is possible by using an external digital transistor at the ground pin.

• Easy paralleling of drivers to increase current
• High current accuracy at supply voltage variation
• No EMI
• Reduced output current at higher temperatures - negative thermal coefficient of -0.3%/K
• Homogenous light output despite varying forward voltages in different LED strings
• Homogenous light output of LEDs despite voltage drop across long supply lines
• Homogenous light output independent from supply voltage variations
• Smaller form factor
• Better quality due to less soldering points
