Notes: 1. Output ltering capacitor C2 is an electrolytic capacitor, It is recommended to use high frequency and low impedance electrolytic capacitors. For capacitance and current
of capacitor please refer to manufacture’s datasheet. Voltage derating of capacitor should be 80% or above. C1 is used to lter high frequency noise. TVS is
recommended component to protect post-circuits (when converter fails).
2.
All specications measured at Ta=25C, humidity <75%, nominal input voltage, and rated output load, unless otherwise specied.
