3) Recommended Circuit
If you want to further decrease the input/output ripple, a capacitor filtering network may be connected to the input and output ends of the DC/DC
converter, see (Figure 3).
It should also be noted that the capacitance of filter capacitor must be proper. If the capacitance is too big, a startup problem might arise. For every
channel of output, provided the safe and reliable operation is ensured, the recommended capacitance of its filter capacitor sees (Table 1).

Note: # for each output. It’s not recommended to connect any external capacitor in the application field with less than 0.5 watt output.
4) The input and the output of the product are recommended to be connected to ceramic capacitor or electrolytic capacitor. Using tantalum
capacitor may cause risk of failure
5) It is not recommended to increase the output power capability by connecting two or more converters in parallel. The product is not
hot-swappable
Note:
1. Operation under minimum load will not damage the converter; However, they may not meet all specifications.
2. Max. Capacitive Load is tested at nominal input voltage and full load.
3. Unless otherwise noted, All specifications are measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load.
4. In this datasheet, all test methods are based on our corporate standards.
