Question about MP2333C RT resistor on the Feedback Network

Dear support member,

Question about MP2333C RT resistor on the Feedback Network.

What is the role of this RT resistor on the Feedback Network of MP2333C?

What is for purpose?

Best regard.

Hi Hideyuki,
Apologies for the delayed response as the factory is on holiday shutdown. For your question, the RT resistor is for loop stability and to limit current going into the FB pin. A higher RFB1 and RT combo indicates a lower bandwidth.

Dear Cecilia

Thank you very much for your answer.

Best regard.
