DESIGN CONSIDERATIONS
1) Requirement for output load
To ensure this module 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, or use our company’s products with a lower rated output
power
.
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) Output Voltage Regulation and Over-voltage Protection Circuit
The simplest device for output voltage regulation, over-voltage and over-current protection is a linear regulator with overheat protection which is
connected to the input or output in series (Figure 4)and an capacitor filtering network.the recommended capacitance of the capacitor refer to Table 1,
linear regulator based on the actual voltage and current to make a reasonable selection.

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.
