Part Number: Ucc28700
May you provide ckt diagram and transformer design details along with a working prototype for an Smps with following specs?
Input 85- 265v/50hz ac
output- 14v 5a CCCV
Shree goriya systems
Thank you for interest in our product. We have worked out the closest reference design to meet your requirements, and you will just need to modify some component values to get +14V/5A output, please see details below:
Product Folder: http://www.ti.com/tool/PMP10350
User Guide: http://www.ti.com/lit/pdf/tidu717
BOM: http://www.ti.com/lit/pdf/tidrcc8 (including the transformer part number)
Modifications to achieve +14V/5A CC/CV:
And I am sorry to inform you we do not have any test board for the PMP designs. You may need to build your own board with all the information you needed under the PMP10350 product folder.
I hope this answers your question and please do not hesitate to contact us if further support is needed.
Thank you very much.

In reply to Nanda Ballabh Joshi:
Please refer to the RLTI-1119 X'FMR datasheet link below:
Npri: Naux: Nsec=9:1:1
Thanks for providing transformer datasheet.
Our transformer manufacturer still have some doubts such as-
Number of turns in P S & A windings
May you pls guide?
The magnetising inductance is listed as 120uH and leakage 4uH in that datasheet. You will need to contact Renco for samples to evaluate or for further information.
Thanks for providing the information, we will find your regional support FAE and sales for you.
Also, you may find this contact information useful if you have any further questions regarding the X'FMR design.

Thank you very much for supporting TI.
In reply to John Stevens:
Thanks for reaching us again!
And I felt sorry to inform you we do not have the information for actual wire size and observed turns for RLTI-1119 either.
I would suggest you reach Renco Electronics for requesting the transformer samples or ask any technical inquiry regarding the RLTI-1119 transformer via firstname.lastname@example.org.
In the meanwhile, I will get the sales team involved to see if we can work out an alternative here.
