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
