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
ƒ Operating voltage 4.5V ~6.8V
ƒ Operating current < 1.2mA @VDD=5.0V, no load
ƒ Support two output mode : (1) PWM Dim Mode, (2) Direct/Toggel Mode.
ƒ Small adjusts duty rate 0.2%.
ƒ Support two dimmer speeding as 6 sec and 12 sec lightness circulation.
ƒ PWM output control NMOS or Direct output mode.
ƒ Memorize turn on.
ƒ Two turn off modes: delay off and non-delay off
ƒ Two input dimmer modes: touch plate and switch
ƒ Two dimmer mode Cycle and Non-Cycle
ƒ Support Touch Direct Mode Function
ƒ The application circuit is simple and easy.
ƒ Can use wire to connect the IC to touch plate.


APPLICATION
ƒ DC LED LAMP
ƒ For PWM control output
ƒ Direct/Toggle Mode output
