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:

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.

5. All characteristics are for listed models, and non-standard models may perform differently. Please contact our technical support for more detail.

6. Please contact our technical support for any specific requirement.
