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

(5).PWM Duty Rate Active High
a. Adjusts rate: 3% ~98% in change rate 0.2%.
PWM DIMMING
Fpwm = Fosc/1072
TTP112
Note : if Fosc = 1.2MHZ Æ Fpwm=1.2KHz
3. TTP112 : Touch Direct/Toggle Mode Function
(1) Touch Direct output, active High (OPT1=1).
a. Touch detect time is 56ms (typical). There is “BI” sound from buzzer when it detects touch.
b. Touch release detect time is 46ms (typical).
