BCR405U Product details

General Description

The BCR405U 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 BCR405U 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 BCR405U 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.



Features

• LED drive current of 50mA

• Output current adjustable up to 65mA with external resistor

• Supply voltage up to 40V

• Easy paralleling of drivers to increase current

• Low voltage overhead of 1.4V

• High current accuracy at supply voltage variation

• No EMI

• High power dissipation of 750mW

• Reduced output current at higher temperatures - Negative thermal coefficient of -0.2% / K

• RoHS compliant (pb-free) small and robust SC-74 package

• Qualified according to AEC Q101



Applications

• Channel letters for advertising, LED strips for decorative lighting

• Aircraft, train, ship illumination

• Retrofits for general lighting, white goods like refrigerator lighting

• Medical lighting

• Automotive applications like CHMSL and rear combination lights
