LED Driver

Features

Applications

General Description

The BCR405U 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 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.

(negative thermal coefficient)

Low voltage overhead of 1.4V

No EMI

High power dissipation of 750mW

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

Qualified according to AEC Q101

Channel letters for advertising, LED strips for decorative lighting

Aircraft, train, ship illumination

Automotive applications like CHMSL and rear combination lights

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

High current accuracy at supply voltage variation

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

Retrofits for general lighting, white goods like refrigerator lighting

Medical lighting

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

lower assembly cost

smaller form factor

better quality due to less soldering points

higher output current accuracy due to pretested LED drivers
