Hello,

Here's a TPS92682 Reference Design that has design equations to help you with the SEPIC desigm.

Hi Tuan

I think your reference design refers to TPS92682Q1 while I am asking about TPS92692Q1 sepic peripheral circuit capacitance, inductance, resistance value, is there a misunderstanding? Thank you.

Hello,

We do not have a SEPIC design for the TPS92692 and that's why I refer you to the TPS92682 TIDA which has equations in there to help you with the power stage design.

Thanks Tuan

Hi Tuan

Thanks for your confirmation. Since I see the block diagram in datasheet:

So just would like to ask about the recommend values. So do you mean if I would like to get the parameters, should I refer to the TPS92682Q1 SEPIC reference design? Thank you.

Hello,

Yes, you can use the design example in the data sheet to get the power stage values and the data sheet to get the other values.

Thanks Tuan
