BCR421UW6 Datasheet Linear Led Constant Current Regulator

Manufacturer: Diodes Incorporated

Overview: BCR420UW6 / BCR421UW6 LINEAR LED CONSTANT CURRENT REGULATOR IN.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General 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.

It is designed for driving LEDs in strings and will reduce current at increasing temperatures to self-protect.

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.
