The LM5022 is a boost controller and the minimum output voltage is restricted to 6V. For above buck condition, following devices can be used to create a design.
1.LM5117
2.LM5088-1
3.LM5088-2
4.LM5145
5.LM5116
6.TPS40170.
Please use the below link to create a design as per your conditions.
I apologies, I did not mention an important factor - the power supply has to be isolated. Using the wizard I get 43 suggested designs, but none of them is based on an off-the-shelf transformer, some are also missing MOSFETs and diodes. Is there an app note for parallel connections to achieve more power? LM5020 looks like a good candidate.
Hi Boaz,
I was able to pick the UCC28C40-Q1 for a 10V to 60V input and 3.3V @9.1A. Yes, in many cases it might be hard to find an exact off-the-shelf transformer that would meet the design requirements. However, many of our high voltage products have capability to recommend a core and bobbin with the winding details that can help you wind the transformer. Also, some of the MOSFETs and diodes could be custom. It is a limitation where the design could not find these high voltage components in our database.
I am having problem opening the design, I tried Firefox, Chrome and IE. The first page pops up a message saying it might take 30 sec, but then it immediately redirects to page that returns HTTP 500 error.
