TTP112
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 NMOS or Direct output mode.
 Memorize turn on.
 Two turn off modes: delay off and non-delay off
 Two input dimmer modes: touch plate and switch
 Two dimmer mode Cycle and Non-Cycle
 Support Touch Direct Mode Function
 The application circuit is simple and easy.
 Can use wire to connect the IC to touch plate.
APPLICATION
 DC LED LAMP
 For PWM control output
 Direct/Toggle Mode output
