BCR402R

概要

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
