General Description
The BCR401R is a cost efficient LED driver to drive low power LED’s. The advantages
towards resistor biasing are:
• homogenous light output despite varying forward voltages in different LED strings
• homogenous light output of LED’s despite voltage drop across long supply lines
• homogenous light output independent from supply voltage variations
• longer lifetime of the LED’s due to reduced output current at higher temperatures
(negative thermal coefficient)

The advantages towards discrete solutions are:
• lower assembly cost
• smaller form factor
• better quality due to less soldering points
• higher output current accuracy due to pretested LED drivers
Dimming is possible by using an external digital transistor at the ground pin.
The BCR401R can be operated at higher supply voltages by putting LED’s between the
power supply +VS and the power supply pin of the LED driver. You can find further details
in the application note AN066.
The BCR401R is a perfect fit for numerous low power LED applications by combining small
form factor with low cost. These LED drivers offer several advantages to resistors like
significantly higher current control at very low voltage drop ensuring high lifetime of LED’s.
