TTP112 - TONTEK

TTP112 CONTINUOUS TOUCH DIMMER

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 ƒ Operating voltage 4.5V ~6.8V ƒ Operating current < 1.2mA @VDD=5.0V, .
