BCR401U, BCR402U, and BCR405U LED Drivers

Diodes’ constant current regulators with preset 10 mA, 20 mA, and 50 mA regulations, respectively, for driving low-power LED strings

Image of Diodes' BCR401U, BCR402U, and BCR405U LED DriversDiodes' BCR401U, BCR402U, and BCR405U constant current regulators provide a simple means of driving low current LED strips and panels in commercial and industrial lighting sectors, particularly suiting those applications that benefit from the improved efficiency, flexibility and longer life offered by LEDs as an emerging lighting source.

Targeted at 12 V and 24 V linear LED strips, these regulators increase light output efficiency as they only require 1.4 V supply allowing more LEDs in the string. Supporting adjustable currents from 10 mA to 100 mA allow for platform designs based on a single device to be used across multiple LED strip applications, considerably easing a manufacturer’s qualification and supply chain.

These LED drivers also enhance system reliability as the monolithic integration of a transistor, diodes, and resistors both simplify system design and reduce component count. These LED drivers are targeted at 12 V and 24 V linear LED strips and panels.

Features
  • 10 mA to 100 mA fixed current
    • Simplify LED driving as current is preset for 10 mA, 20 mA, and 50 mA with ±10% regulation and the flexibility to adjust up to 100 mA
  • Negative temperature coefficient
    • Reduces the current with rising temperature, which helps to increase the ELD lifespan
    • Enables current sharing for paralleled operation for >100 mA LED current
  • 1.4 V to 40 V supply voltage
    • Increases light output efficiency as only 1.4 V supply required, allowing more LEDs in the string
    • 40 V gives sufficient headroom for voltage spikes and LED short failures, while preserving the LED brightness and longevity
  • PWM <1% duty cycle at 25 kHz
    • LED brightness can be accurately PWM controlled allowing low light dimming
Applications
  • Advertising signage
  • Emergency lighting strips
  • Refrigeration and vending machines
  • Building light strips
  • Architectural and decorative
  • General lighting
