Triac Dimmer Constant Current Led Driver

Leading edge dimming and trailing edge dimming.

Triac dimmer constant current led driver.

It then commands the leds to dim to that level such as with pwm or current limiting. The dim decoder allows wide range led dimming using standard triac dimmers. 120v 220 240v 277v. Dimmable models feature smooth dimming and compatibility with leading dimmer brands.

A dimmer friendly led driver is generally one which is hardened and also has some intelligence to listen to the ac waveform and reverse engineer what the triac dimmer is trying to do. The lm3445 is an adaptive constant off time ac dc buck step down constant current controller designed to be compatible with triac dimmers. When such fluctuations occur the led driver will compensate so that the power being supplied to your leds remains constant. 6w 8w 150ma constant current source triac dimmable led driver efficiency 84 pf 0 91 38 50v output voltage 8w output power 150ma output current solated designing solution compliance to worldwide safety regulations for lighting high efficiency power supply 12v 24w triac dimmable led driver for led transformer item no smt 012 024vt.
