All the IGBT driver of this series are tested according to the recommended circuit (see Fig. 2) before delivery.

If it is required to further reduce input and output ripple, properly increase the input & output of additional capacitors Cin and Cout or

select capacitors of low equivalent impedance provided that the capacitance is no larger than the max. capacitive load of the product.

EMC solution-recommended

Note: Part ① in the Fig. 3 is used for EMS test ; part ② and part③ are used for EMI

filtering; selected based on needs.
