I would like to adjust DC2821A Vout from 12V to 15V. Require to modify the feedback resistor.
However, DC2821A transformer - Sumida 12301-T223 does not have any datasheet and detail. We cannot find any detail online and sumida website.
Might I know if you have any detail for 12301-T223? We require to have tune ratio for adjusting Vout.
From our reverse calculation with feedback resistor 178k, tune ratio is around 4:3 or 5:3.
Appreciate your help in advance.
