The UCS1903B and UCS1903N similarities:
1. SOP8 Package,Single data signal SPI protocol.
2. PWM scanning frequency Fpwm=1.5Khz
3. Support high speed mode 800kbps data rating.
4. 3 Channel constant current output, default current 17mA/CH
5. Self inspection when power on. blue color light on.
6. Data Format and Pluse width timing, The data endoing adopt unipolar RZ code.
7. The data transmision method.
8. 8bit/color,256 Grayscale.
The UCS1903B and UCS1903N Difference
1.The output ports withstand max voltage value.UCS1903B: Max 24V; UCS1903N:Max 30V
2. The IC working voltgae. UCS1903B Vdd range from 2.5V to 6.5V;UCS1903N Vdd range from 3V to 6V.
The conclusion: UCS1903B is suitable for 5V,12V Circuit, UCS1903N is suitable for 5V,12V,24V circuit.
