RECOMMENDED CIRCUIT
If you want to further decrease the Input surge current and output ripple, an 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 2).

Note:
1. The load shouldn't be less than 5%, otherwise ripple will increase dramatically.
2. Max. Capacitive Load is tested on Vin-nominal and full load.
3. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
4. In this datasheet, all the test methods of indications are based on corporate standards.
5. Only typical models listed, other models may be different, please contact our technical person for more details.
6. Specifications subject to change without notice.
