Description

0%-100% full PWM/analog dimming, no flicker and noise free

Thanks to the innovative full-range analog dimming technology, MT971XB achieves flicker-free, noise-free, fine and smooth dimming, as well as good current consistency during deep dimming, such as 1% dimming depth at ± 5% current accuracy, greatly improving the using experience.

Full range reliable OVP

MT971XB realizes full range reliable OVP by adopting the innovative OVP technique, even in small night light mode. Besides, the OVP function is moisture-proof and noise immune.
