TYPICAL APPLICATIONS
1. Output filtering capacitors C1 is electrolytic capacitors, It is recommended to use high frequency and low impedance electrolytic capacitors. For capacitance and
2. MOV is required to LD10 models, model: 471KD05, it is used to protect the device under surge.
3. It is recommended to connect FUSE, the parameter is 2A/250V slow blow. External input NTC model is recommended to use 5D-9.
4. If common requirement to EMC performance, refer to figure 1, if higher requirement to EMC performance, refer to figure 2.
OUTLINE DIMENSIONS & PIN CONNECTIONS
Note:
current of capacitor please refer to manufacture’s datasheet. Voltage derating of capacitor should be 80% or above. C2 is ceramic capacitor, it is used to filter
high frequency noise. TVS is a recommended component to protect post-circuits (if converter fails).
