Power Switch Sensing LED Lighting Control Chip
Descriptions of Product
 TTY5003 is an LED lighting control chip that can detect the switching of power supplied by
city electricity. The ON/OFF switching within the preset time can control the output modes of
the LED lighting, with control of single and double lights, where the single light mode can
control 3 levels of brightness while the double light mode can be implemented in lighting with
double colors for hue control of different light sources. Such functions can control the
brightness or change the light color for enriched life.
Features of the Product
 Operating Voltage：2.4V - 5.5V
 Applicable to three LED switching modes: single light control mode, single light double colors
control mode, and double light switching control mode
 One can select single light double colors control mode or double light switching mode through
the OPT pin. The single light control mode has its own independent OPT pin selected as Low
 Each LED switching mode has three levels of output for selection
 Use the Power switch to select the method of LED output
 Automatic light off in power outage
