... Green Product (RoHS Compliant) Description The TLD5085EJ is a smart LED buck converter with an integrated power-switch, capable of driving up to 1.8A load current with excellent line and load regulation. The main function of this device is to step-down the input voltage and regulating a constant LED current. The constant current regulation is especially beneficial for LED color accuracy and longer lifetime ...
