This series should be tested under load & never be tested under no load (See Figure 1). Figure 1 - Single Output If you want to further decrease the input/output ripple, you can increase capacitance properly or choose capacitors with a low ESR. However, the capacitance should not be too high.(See table 1). Input Current When it is used in an unregulated power supply, be sure that the fluctuating range of the power supply and the rippled voltage do not exceed the module standard. Input current of power supply should afford the startup current of this kind of DC/DC module. (See figure 2) Figure 1 - Dual Output External Capacitor Although this series of DC/DC converters can work without an external capacitor, it is highly recommended to use one in order to keep an optimum performance. (See Table 1) Requirement on Output Load To ensure this module operate efficiently and reliably, a minimum load is specified for this kind of DC/DC converter in addition to a maximum load (namely full load). During operation, make sure the specified range of input voltage is not exceeded, the minimum out put load is not less than 10% Of the full load, and that this product should never be operated under no load!!! If the actual load is less below the specified minimum load, the output ripple of this type of DC/DC converter will increase drastically and at the same time efficiency & reliability of the circuit will decrease deeply .If the actual output power from the load in your circuit is very small, please connect a resistor with proper resistance at the output end in parallel to increase the load, or use our company’s other products with a lower rated output power.
