TPS56C230: Component Review

Tom Schultz

Part Number: TPS56C230

Hello,

I'm posting on behalf of my customer. Could you review the component value selection for the 2 rails using the TPS56C230? Please see attached word doc for Vin, Vout, Iout and component values.

Thanks,

Hi Tom,

Have you tried checking out the WEBENCH design for the part for these specs? This would be the quickest way to get to the design.

regards,

Gerold

Gerold,

Yes, the customer already used our power stage designer tool, but would like a second opinion from a power specialist familiar with this part to give him confidence and move forward. Is this something you're able to help with?

Thanks,

Tom

Tom,

Most are OK, just found the inductor you chose maybe a little bigger, please provide input voltage range to double check.

Yuchang,

Thanks for your response. I've attached a word doc with details on how the inductor values were derived. I look forward to your feedback on the appropriate inductor TPS56C230 review v2.docxsize.

Tom, For ripple and stable performance, it is ok, but as we know big inductor will cause lower transient response, so if you application is not very care about transient, it is ok.
