Typical Application Circuits

EMC parameter recommendation

Component No.	Function	Recommended value
Fuse	Protest the circuit from damage when the module is abnormal	2A/250Vac, Slow fuse
Varistor	The cumulative surge is to protect the module from damage	10D561K
C1/Safety capacitance	Filtering, safety protection(EMC certification)	0.1uF/275Vac
L1/Common-mode inductance	EMI filtering	Sensible value 10-20mH, current 1-2A

Notes：

* Fuses and varistors are basic parts of protection circuits (required).

* If the certification is required, the safety capacitor and common mode inductance cannot be omitted.

Output filtering

For usual requirements of ripple and noise, the peripheral recommendation is only C2; For strict requirements of ripple and noise, the above circuit is recommended. Notes:

(1) C2, C3 use high frequency low resistance electrolytic capacitor, and the total capacity can not exceed the maximum capacitive load indicated in the manual, otherwise the module will not start normally. (2) When the capacitive load is used, the minimum load of 3% must be guaranteed, otherwise the module output will be abnormal.

Component No.	Function	Recommended value
LDM3/Common mode inductance	Adjust the output ripple voltage	Inductance: 0.47-4.7uH according to the debugging result
LDM4/Common mode inductance	Adjust the output ripple voltage	Inductance: 0.47-4.7uH according to the debugging result
C2,C3 Electrolytic capacitor	Ripple voltage filtering	68-220uF/50V
C4 Ceramic capacitors	Ripple voltage filtering	1uF/50V
