Here are presented input current consumption measurements. Current consumption is measured during a LED blink program execution. Program code sets every LED output to full PWM value for 2 seconds and then PWM is set to 0 for 2 seconds. This is looped endlessly. 750 measurements are taken during one measurement cycle. Figure 9. Input Current Consumption in Power Save Mode With External Clock Running, no LEDs as Load and no LED Drivers are Enabled During Program Execution. 6.10 Typical Characteristics: LED Output LED driver typical performance images. Figure 10. Every LED Driver Saturation Voltage, Current Setting 17.5 mA Figure 11. LED Driver Currents Compared to Current Setting Code Figure 12. LED Driver Current Accuracy With Different Current Setting Figure 13. LED Driver Current Matching Between all LED Drivers With Different Current Setting |
