TFS2 designing

Posted by: wang zhihua on 08/30/2016

HI,

I'm designing a power unit with a 12V/0.5A standby and a 36V main output. the main output is controlled by MCU,when it outputs,it will output 1 minutes,then turn off.the load current is about 6A,but maxim current is 10A(only lasts whithin 2 seconds).I'm going to use TFS2 family,which one should I select in this application?and how to design the main transformer(using EI35)?

TFS7703 or TFS7704 will be good choice to meet with peak pwoer and rated power requirement. Run PIXL design tool will support the transformer design

Thank you,PI-Neela,

I have a question when using PIXL.I find the turns of the secondary output coil of the main transfomer can be selectable by me,and the primary coil turns will change with the selection.so,how many turns are the best selection? wang

if you can share with us your deisgn in PDF with high lighted cells and in actual design file, it is easier for us to address your question.
