Part Number: UCC27282

Tool/software:

In application report SLVA636 Practical Feedback Loop Analysis for Current Mode Boost Converter, DC gain of the converter is given by eq(6), Kdc=(D' x Rload)/Ri, but Ri is not defined anywhere in the document. Does anbody know what "Ri" is?

Hey Nathan,

Thank you for reaching out with your questions.

The UCC27282 is a gate driver than can be used in a boost converter circuit. I have moved this thread to the boost converter group to help with this question.

Thank you,

William Moore

Hi Nathan,

Thank you for reaching out.

Ri is the current sensing resistor here.

Please tell me if you have more questions.

Best Regards,
