LM3445 Overview
The LM3445 is an adaptive constant off-time AC/DC buck (step-down) constant current controller designed to be patible with TRIAC dimmers. The LM3445 provides a constant current for illuminating high power LEDs and includes a TRIAC dim decoder. The dim decoder allows wide range LED dimming using standard TRIAC dimmers.
