The recommended L1 = 22 µH, CBYP = 0.01 µF and low leakage CREF = 10 nF are selected. The minimum recommended CIN = 4.7 µF is selected. To prevent VSTOR from drooping during system load transients, CSTOR is set to 100 µF. To disable the sampling for MPPT, the VOC_SAMP pin is tied to VSTOR. To disable the input voltage regulation circuit, the VREF_SAMP pin is tied to GND. Since the VBAT_UV function is not needed, the VBAT_UV can be tied to VSTOR. To stop charging when the IC junction temperature is above 65°C, the OT_PROG pin is tied to GND.
