Typical Application Circuits
1. General application:
If it is required to further reduce the input and output ripple, a capacitor filter network can be connected to the input and output
ends, and the application circuit is shown in Figure 1.
However, attention should be paid to the selection of appropriate filter capacitors. If the capacitor is too large, it is likely to
cause startup problems. For each output, under the condition of ensuring safe and reliable operation, the recommended
capacitive load value is shown in Table 1
EMI typical application circuit
Notes：Output Load Requirements
In order to ensure that the module can work efficiently and reliably, the minimum output load cannot be less than 10% of the rated load when in use. 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 the actual power used, otherwise the temperature of the resistor will be higher).
