Description

The BCR420UW6 and BCR421UW6 monolithically integrate transistors, diodes, and resistors to function as a Constant Current Regulator (CCR) for linear LED driving. Each device regulates with a preset 10mA nominal that can be adjusted with an external resistor up to 350mA.

Key Features

  • LED Constant Current Regulator using NPN Emitter-Follower with Emitter Resistor to Current Limit
  • IOUT - 10mA ± 10% Constant Current (Preset)
  • IOUT up to 350mA Adjustable with an External Resistor (BCR421U)
  • VOUT - 40V Supply Voltage
  • PD up to 1W in SOT26
  • Low-Side Control Enabling PWM Input < 25kHz (BCR421U)
  • Negative Temperature Coefficient (NTC) Reduces IOUT with Increasing Temperature
  • Parallel Devices to Increase Regulated Current
  • Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
  • Halogen and Antimony Free. “Green” Device (Note 3)
