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 3. Input Current Consumption in Normal Mode With External Clock Running. 4 LEDs (RGBW) Set as Load. Every LED Driver Current Value Is Set to 10 mA. Figure 4. Input Current Consumption in Normal Mode With Internal Clock Running. 4 LEDs (RGBW) set as Load. Every LED Driver Current Value is Set to 10 mA . Figure 5. Input Current Consumption in Power Save Mode With External Clock Running, no LEDs as Load. All 4 LED Drivers are Enabled During Program Execution. Figure 6. Input Current Consumption in Power Save Mode With Internal Clock Running, no LEDs as Load. All 4 LED Drivers are Enabled During Program Execution. Figure 7. Input Current Consumption in Power Save Mode With External Clock Running, no LEDs as Load. Only 1 LED Driver is Enabled During Program Execution. Figure 8. Input Current Consumption in Power Save Mode With Internal Clock Running, no LEDs as Load. Only 1 LED Driver is Enabled During Program Execution. |
