LS7642FO Description
LS7642 is an innovative light dimmer allowing direct control of illumination with analog voltage. The analog voltage applied at the brightness control input directly controls the conduction angle of a triac in series with the lamp. For manual dimming applications such as, wall switches, floor and table lamps etc, a sliding or rotary potentiometer with a center tap can serve as the controlling element.
