Touch control lamp step dimmer.

LS7237, TOUCH CONTROL LAMP STEP DIMMER

LS7237 is a monolithic, MOS integrated circuit designed to control the brightness of an incandescent lamp.

The output of the LS7237 triggers a triac connected in series with a lamp(See Figure 5).

The lamp brightness is determined by controlling the output conduction angle (triac triggering angle) i

LS7237 Features

* PLL synchronization allows use as a Wall Switch

* Provides brightness control of an incandescent lamp with a touch plate or mechanical switch

* Can control speed of shaded pole and universal AC motors

* Controls the "duty cycle" from 23% to 88% (conduction angles f
