The TLC5973D is a 3-channel 12-bit PWM constant-current LED Sink Driver for RGB LED cluster lamp displays. The display repeat rate is achieved at 2.9kHz (typical) with an integrated 12MHz grayscale (GS) clock oscillator. The driver also provides unlimited cascading capability. All output sink constant currents can be set by an external resistor. It has an internal shunt regulator that can be used for higher VCC power-supply voltage applications.
- Single-wire interface (EasySet�)
- Integrated shunt regulator
- Output delay switching to prevent inrush current
- Unlimited device cascading
- Up to 21V OUT terminals maximum voltage
- 3Mbps Maximum data transfer rate
- Green product and no Sb/Br
Applications
Commercial, Imaging, Video & Vision
