CONTINUOUS TOUCH DIMMER FOR DC LED LIGHTING
GENERAL DESCRIPTION
The TTP112 is a continuous touch detector IC for the DC LED lightings. The dimmer function controls by PWM output. The PWM duty range is 3% ~98% that is the lighting dimmer as 3% ~98%. It has high frequency and small adjusts duty rate, which can let the LED lighting dim smoothly.
Features
- Operating voltage 4.5V ~6.8V
- Operating current < 1.2mA @VDD=5.0V, no load
- Support two output mode : (1) PWM Dim Mode, (2) Direct/Toggel Mode.
- Small adjusts duty rate 0.2%.
- Support two dimmer speeding as 6 sec and 12 sec lightness circulation.
- PWM output control...
