Preliminary Datasheet
16-Channel Low Knee Voltage PWM Constant Current LED Driver for Low Voltage Power Supply, 1:32 Time-Multiplexing Applications
Features
- 3V-4.2V supply voltage
- Design optimization
- 16 constant current output channels
- Constant output current range:
- 0.5~10mA @ 4.2V supply voltage
- 0.5~5mA @ 3.3V supply voltage
- Low knee voltage of output channels VDS=0.3V @ IOUT = 10mA, VDD=4.2V
- Excellent output current accuracy: Between channels:：<±2.5％(Max.) Between ICs: <±3％(Max.)
- Built-in 16K-bit SRAM to support time-multiplexing for 1 ~ 32 scans
- 16-bit/14-bit /13-bit color depth PWM control to improve visual refresh rate
- 6bit current...
