Other Parts Discussed in Thread: UC1843-SP, TIDA-070002, UC1843, UC1901-SP
Hi,
I have a customer interested in the UC1843-SP.
Please help answer the following question.
I saw the sample circuit in the datasheet and the TIDA-070002 circuit, I’m not quite sure about the use of coupler for feedback. I see that the input to FB pin in UC1843 had been isolated but what is the reason for isolation? Is it really required?
Thanks,
Needhu
