PMP4190: Reference design File PMP4190

Hi,

I have design SMPS using of PMP4190.

I/P-3 VDC to 6VDC

O/P-5V/400mA with 1500VDC isolation

I am structing Transformer. As per reference design I am not found transformer and not available stock.

So Please me suggest alternate part number of transformer.

OR share me transformer design file.

Thanks for Suggestion.

I have also seen datasheet.

How many turns will the primary  and secondary winding of the transformer?

I am coordinate GCI but still now I am waiting reply for GCI.

If you have alternate part number transformer instead of GCI Transformer .Please reply me.

Hi Navi,

The turn ratio is 1:2.5 (pri:sec), but we do not have the internal construction details for the transformer to know the exact number of turns. GCI would need to provide these details. 

I am sorry, but we do not have a second source for this transformer for this design.

Another solution for this input/output is the SN6501-MULXFMR-EVM (configuration #4). Here is a link to the design.

If you don't need to run all the way down to 3V on the input, we might have other solutions to offer.

thanks,

Brian

Yes 

I have also another solution SN6505B as similarly to your solutions.

I have also coordinator GCI but They are no reply my quarry.

You have contact any GCI Person
