LS7231-7234 - TOUCH CONTROL LAMP DIMMER
LS7231 through LS7234 are a series of monolithic, MOS integrated circuits designed for the control of brightness of incandescent lamps.
The outputs of these ICs control the brightness of a lamp by controlling the firing angle of a triac connected in series with the lamp.
All internal timings are sy
