UC1825: Recommendation requests and technical support requests for values of R and C located between EAOUT and INV pins.

Hello

Thank you for responding to my previous inquiry.

I'm writing to ask you some additional questions.

1. You said that R and C are required between EAOUT and INV pins, Can you recommend the appropriate R and C values for the above circuit?

2. In the above circuit, the output of EAOUT pin is 5V in normal operation and 2V in abnormal operation.(The output is reduced.) I was wondering if the R and C between EAOUT and INV have an effect on the reason why the output decreases.

Thank you for your response.

Hello,

Could you provide the powerstage information of your design? i.e. transformer, transformer inductances, output capacitors, etc.

A full schematic would also help.

Thanks,
Mujtaba
