General Description
The BCR402W 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

FEATUREs
• LED drive current of 20mA
• Output current adjustable up to 60mA with
   external resistor
• Supply voltage up to 18V
• Easy paralleling of drivers to increase current
• Low voltage overhead of 1.2V
• High current accuracy at supply voltage variation
• No EMI
• Reduced output current at higher temperatures - negative thermal coefficient of -0.3% / K
• RoHS compliant (pb-free) small SOT343 package
• Qualified according 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
