Note the following when changing from EN5337QI to EN6347QI.

• Change the values of RA, RB, and Ca because they affect circuit stability.

－Ra=200kΩ
-Rb = Please calculate according to the output.
－Ca=10pF (standard), please set according to the table of EN6347QI document p16. If the total capacitance exceeds 100uF, please give priority to the table on p17.

• Check the usage range of the SoftStart adjustment capacitor Css.

- The Css capacitance range of EN6347QI is 10nF to 68nF.

• Always connect LLM/SYNC (pin26) to GND.
