General Description
The BCR401U is a cost efficient LED driver to drive low power LED’s. The advantages
towards resistor biasing are:
The advantages towards discrete solutions are:
Dimming is possible by using an external digital transistor at the ground pin.
The BCR401U 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 AN097.
The BCR401U 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.
