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.

LS7231-7234 Features

* Phase-lock loop synchronization allows use in Wall Switch applications.

* Provides brightness control of incandescent lamps with touch plates or mechanical switches.

* Controls the "duty cycle" from 23% to 88% (conduction angles for AC half-cycles between 41˚ and 158˚, res
