Series operation is possible by connecting the outputs of two or more identical devices. The connection is
shown in the following drawing.

Notes:
- Use larger C1, C2, C3, C4, C5 or capacitors in parallel if the impedance of input line is high or unknown.
- Use more than two recommended capacitor above in parallel when ambient temperature becomes lower
than -20 °C.
- Use a Schottky diode (D1, D2) across the output of each device, so that if one converter shuts-down for
any reason, the output converter does not get damaged.
