The “parallel cable” method is used for Ripple and Noise test, please refer to
DC-DC Converter Application Notes for specific information.
With light loads at or below 20%, Ripple & Noise for 3.3V output parts increases
to 100mVp-p max, and a load below 10% for 5V/9V/12V/15V output parts levels
increase to 150mVp-p max.

1. The required C1 and C2 capacitors must be connected as close as possible
to the terminals of the module;
(ceramic capacitor) (ceramic capacitor)
2. Refer to Table 1 for C1 and C2 capacitor values. For certain applications,
increased values and/or tantalum or low ESR electrolytic capacitors may
also be used instead;
3. Converter cannot be used for hot swap and with output in parallel;
4. To further reduce the output ripple and noise, we suggested the use of
a “LC” filter at the output terminals, with an inductor value (L) of 10µH-
47µH.
