Part Number:TPS55010
Hi, team.
My customers are troubled by the influence of EMI in board design of TPS55010.
Also, the difference of EMI data is between the EVM (ideal pattern) condition and the design circuit of the customer's actual machine,
greatly depends on whether there is a capacitor(Y CAP) between the insulation or not.
So, please tell me about this principle.
＜Question＞
・What principle does fit by attaching a capacitor between insulation?
・Explanation of the insulated capacitor in the data sheet
・(There is no problem even if it is approximated ...) What kind of having to consider are available for capacitor constant setting?
※ Please tell me the formulas or principles
Best regards,
Masumi Sekiguchi
