LS7534 and LS7535 are MOS integrated circuits that are designed for brightness control of in- candescent lamps. The outputs of these ICs control the brightness of a lamp by controlling the firing an- gle of a Triac connected in series with the lamp. All internal Timings are synchronized with the line fre- quency by means of a built-in phase-lock loop cir- cuit. The output occurs once every half-cycle of the line frequency. Within the half-cycle, the output CAN be positioned anywhere between 159 conduction angle for maximum brightness and 41 conduction angle for minimum brightness in relation to the AC line frequency. The positioning of the output is con- trolled by applying the proper Logic levels at the UP and DOWN inputs. By LSI Computer Systems, Inc.
