| Abstract: | The LM3445 is a AC-DC buck （step-down） constant current LED controller designed to be compat-ible with standard TRIAC dimmer. LM3445 includes a TRIAC dim decoder and it allows wide range LED dimming using TRIAC dimmers. The features and application circuit as well as design for circuit are introduced in this paper. |
