PWM-Embedded 3-Channel Constant Current
LED Sink Driver for Small RGB Cluster
Features
3-channel constant current sink driver for RGB LED clusters
Constant current range 5~50mA
Individual output current adjusted through external resistors
Sustaining voltage at output channels: 17V (max.)
Supply voltage 3V~5.5V
Embedded 16-bit PWM generator
- Gray scale clock generated by the embedded oscillator
- PWM counter reset function
- S-PWM technology
Two selectable gray scale modes
- 16-bit gray scale mode (with optional 8-bit dot correction)
- 10-bit gray scale mode (with optional 6-bit dot correction)
Reliable data transmission
- Daisy-chain topology
- Two-wire only transmission interface
- Clock reverse
- Built-in buffer for long-distance transmission
Flexible operation modes
- Auto-synchronization mode
- Manual-synchronization mode
Selectable polarity reversion to drive high-power drivers or MOS
RoHS-compliant packages
Application
Architecture decorative lighting
Mesh display, LED strip
Neon lamp alternative
PWM generator
