VIN_DC = sourcemeter with VSOURCE = 1 V and compliance of
10.5 mA
VBAT = 0.1 F supercap
VSTOR = open to 500 Ω to open resistive load (IL = load current
on VSTOR)
Figure 17. 5 mA Load Transient on VSTOR
VIN_DC = sourcemeter with VSOURCE = 1 V and compliance of
10.5 mA
VBAT = sourcemeter with VSOURCE = 2.8V and compliance
of 1A
IL = inductor current
Figure 18. MPPT Operation
VIN_DC = sourcemeter with VSOURCE = 1 V and compliance of
10.5 mA
VBAT = sourcemeter with VSOURCE = 2.8 V and compliance
of 1A
Figure 19. VRDIV Operation
VIN_DC = sourcemeter with VSOURCE = 1 V and compliance of
2.75 mA
No storage element on VBAT
VSTOR artificially ramped from 0V to 3.15 V to 0 V using a
power amp driven by a function generator
