Typical Application Circuits

ELECTRIC DIAGRAM

EMC parameter recommendation

Component No.	Function	Recommended value
Cin Capacitance	Filter capacitor	4.7μA/50V
Cout Capacitance	Filter capacitor	Refer to usual application
Lin inductance	Filter inductance	Inductance: 4.7uH
Lout inductance	Cin Capacitance	Inductance: 4.7uH

Notes：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)
