DESIGN CONSIDERATIONS
1) Requirement for output load
To ensure this module can operate efficiently and reliably, the minimum output load could not be less than 10% of the full load. If the actual
output power is very small, please connect a resistor to the output in parallel to increase the load.
2) Overload Protection
Under normal operating conditions, the output circuit of these products have not overload protection. The simplest method is to add a breaker
circuit in the circuit.
3) Recommended circuit
If you want to further decrease the input/output ripple, an capacitor filtering network may be connected to the input and output ends of the
DC/DC converter, refer to Figure 3.
It should also be noted that the capacitance of the capacitor must be proper. If the capacitance is too large, a startup problem might arise.For
ensuring every channel of output can provide a safe and reliable operation , the recommended capacitance of the capacitor refer to Table 1.

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.
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.
7. Specifications of this product are subject to changes without prior notice.
