Remarks
1.Output filtering capacitor C5, 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 PPM10 model and PPM15 model)
