LS7540 Datasheet (LSI) - TOUCH CONTROL CONTINUOUS DIMMER

LS7540, TOUCH CONTROL CONTINUOUS DIMMER

The LS7540 is a CMOS integrated circuit for controlling the brightness of incandescent lamps with momentary touch.

When its TOUCH input is connected to a lamp body, the entire lamp turns into a touch plate.

A built-in AGC circuit allows for a wide range of lamp sizes to be used, ranging from very s
