BCR405U LED driver, low side, SOT-23-6

The BCR405U is a low-cost LED driver for low-power LEDs.

The advantages over series resistors are: - Homogeneous light output despite different forward voltages in different LED strings - Homogeneous light output from LEDs despite voltage drop across long supply lines - Homogeneous light output independent of variations in supply voltage - Longer service life of LEDs due to reduced output current at higher temperatures (negative temperature coefficient)

The advantages over separate solutions are: - Lower installation costs - Smaller format - Better quality due to less soldering points - Higher verified output current due to pre-tested LED drivers

Dimming is achieved using an external digital transistor on the earth pin.

Applications: - LED strip for decorative lighting - Plane, train, ship lighting - Retrofits for general lighting, white goods, such as refrigerator lighting - Medical lighting - Automotive applications
