■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 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 near to the converter pin side, to lower the lead inductance.
