Description
The BCR405UW6 monolithically integrates a transistor, diodes and resistors to function as a Constant Current Regulator (CCR) for LED driving. The device regulates with a preset 50mA nominal that can be adjusted with external resistor up to 65mA. It is designed for driving 0.25W LEDs in strings and will reduce current at increasing temperatures to self-protect. Operating as a series linear CCR for LED string current control it can be used in applications with supply voltages up to 40V.
With no need for additional external components, this CCR is fully integrated into a SOT26 minimizing PCB area and component count.
Application
- Constant current regulation (CCR) in:
- Emergency lighting
- Signage, advertising, decorative and architectural lighting
- Retail lighting in fridge, freezer case and vending machines
