Notes: Ripple and Noise Test Methods Twisted Pair Test Method
Note:
1、The above is only a list of typical products. If you need products beyond the list, please contact our sales. 2、The maximum capacitive load indicates the maximum capacitive load that + VO or - vo can be connected to,If the value is exceeded, the product will not start normally..
Typical Application Circuits
1. Routine application:
If it is required to further reduce the input and output ripple, a capacitive filter network can be connected at the input and output terminals, and the application circuit is shown in Figure 1.
However, attention should be paid to the selection of appropriate filtering capacitors. If the capacitor is too large, it is likely to cause startup problems. For each output, the recommended capacitive load value is shown in Table 1 under the condition of safe and reliable operation.

3. Output Load Requirements
In order to ensure that the module can work efficiently and reliably, the minimum output load should not be less than 10% of the rated load.If the power you need is really small, please connect a resistor in parallel between the positive and negative poles of the output terminal (the sum of the actual power used by the resistor is greater than or equal to 10% of the rated power and the rated power of the selected resistor must be greater than 5 times of the actual power used, otherwise the temperature of the resistor will be higher)
Product appearance size and pin definition, suggested printing layout
*Note: If the definition of each pin of the power module is inconsistent with the selection manual, the label on the physical label shall prevail.
