■Standard usage instructions
The CHVM series does not require any external parts, however when the impedance is high, for example:
the distance between the power supply and converter is long, the input line is thin, or the input side has a filter
then connecting a capacitor C1 to the input side is recommended.
Place the capacitor as close as possible to the converter pin side, to lower the lead inductance.
