TLD5045EJ Description
The TLD5045EJ is a highly integrated smart LED buck controller with built in protection functions. The main function of this device is to drive single or multiple series connected LEDs efficiently from a voltage source (VS) higher than the LED forward voltage by regulating a constant LED current (ILED). The constant current regulation is especially beneficial for LED color accuracy and long LED lifetime.
