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.

LM3445 Key Features

  • 270VAC Capable of controlling LED currents greater than 1A Adjustable switching frequency Low quiescent current Adaptive
