UC1825B-SP: I try to get Buck application design notes

Hey Benjamin,

There is no buck application note for the UC1825B-SP.

Do you have approximate specifications for the topology?

Depending on efficiency requirements/schedule our TPS7H5001-SP may be a better option.

Thanks,

Daniel

Thank you, Daniel.

Here is my connection example. Please let me know if this is ok. 

Thanks

Ben

Hey Ben,

This is a UC1843B-SP design.

Is this the correct design?

Daniel,

Yes, I got this design sample for a Buck. 

Daniel,

Do you think it is not right? Why?

Thanks,

Hey Benjamin,

The design you show is using a different part than the one you listed.

That is why I questioned if it the correct design.

The design it self is somewhat confusing, because the ramp signal generated into the ISENSE pin can likely get above the 1 V threshold of the pin which seems undesirable when you are trying to force the COMP pin.

Thanks,

Daniel
