LS7231 - TOUCH CONTROL LAMP DIMMER

General Description

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.

Key Features

  • Phase-lock loop synchronization allows use in Wall Switch.
