4.1 Test Waveform

To meet the nature environment, system working waveforms are tested under different lighting and load conditions for comparison.

Figure 4-1 shows the supercap charging process under strong light conditions. When the device is enabled, super cap started to charge. The switch current shows the mode switch of TPS61094 and the solar panel voltage is regulated at 4.8 V(MPPT point). And the output voltage is stable.
