LM25184: Is SSR Possible, or Other Ways to Improve Regulation Accuracy?

Part Number: LM25184
Other Parts Discussed in Thread: LM25017

The datasheet states 1.5% accuracy.

I believe with output of ~ 4V, that's about 60 mV tolerance.

I need to double or better the accuracy. Any way?

Also, can Vout be adjusted during operation?

Hello

I assume this is the same application as your other post.

I would appreciate if you could close one post and we can work

with the other.

I don't think that the accuracy can be improved since the feedback

architecture on this device is unique.

Thanks

But that's a different part. This forum is set up so each question is about a specific part. I'm required to enter a part number when i create the post.

This question is about LM25184. That other question is about LM25017.

Hello

I don't think that the accuracy can be improved since the feedback

architecture on the LM25184 device is unique. With the LM25017 using fly-buck, the

secondary is only loosely regulated.

Thanks
