Remark：
1. Output filtering capacitor C3 and C1 are electrolytic capacitor. It is recommended to use high frequency and low resistance electrolytic capacitor. For capacitance
and current of the capacitor please refer to suppliers’ specifications. Voltage derating of capacitor should be 80% or above. C2, C4 and C6 eliminate high
frequency noise. TVS is a recommended component to protect post-circuits (when converter fails).
2. External input NTC is recommended to use 5D-9 ( Only LB10 models)
