Test Summary
Figure 6. Basic Switching Converter, Vin = 1V, Vbat = 2.5V
Note here that V
IN
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.
