LS7232ND Description
LS7232ND is a MOS integrated circuit designed to control brightness of incandescent lamps. The output of this IC controls the brightness of a lamp by controlling the firing angle of a triac connected in series with the lamp. All internal timings are synchronized with the line frequency by means of a built-in phaselock loop circuit.
LS7232ND Key Features
- Phase-lock loop synchronization allows use in Wall Switch
LS7232ND Applications
- Provides brightness control of incandescent lamps with touch plates or pushbutton switches
- Controls the duty cycle from 23% to 88% (conduction angles for AC half-cycles between 41˚ and 158˚, respectively.)
