BCR402R
概要
詳細:
The BCR402R is a cost efficient LED driver to drive low power LEDs.
特長:
- 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) SOT143R package
- Qualified according AEC Q101
利点:
- 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)
ターゲットアプリケーション:
- Channel letters for advertising, LED strips for decorative lighting
- Aircraft, train, ship illumination
- Retrofits for general lighting, white goods like refrigerator lighting
- Medical lighting
