Figure 6.

When Setting the Output Voltage to 3.0/3.8V

Note 10.

: Power supply of the startup circuit. The supply source is P.V.

: Power supply of the Internal circuits, VB pin and SEL pin for pull up.

Note 11. Select the C1 value to prevent the LC pin voltage from exceeding the absolute maximum rating due

to the current through parasitic capacitance of the external load switch.
