Test Summary

Figure 6. Basic Switching Converter, Vin = 1V, Vbat = 2.5V

Note here that V

is regulating at the MPPT threshold so the boost circuit is delivering the maximum

power that the source can deliver. The user can see after about 4 pulses that the switching waveforms

stops which cause the inductor to go discontinuous and ring.
