Hi, we are using the Würth 750315240 transformers in series to build a high voltage isolator.
It works really well with the LT3439, but now we want to try the 6505A. WIth the LT chip, we cut all center tabs apart from the first one on the primary side, and reduced switching frequency to 100kHz.
With the 6505A, we are running into heat issure quickly, even at 100mA output. I wonder if the 6505A needs the center tabs to be connected all the way to the secondary side.
Should I try that? Any experience with multiple transformers in series?
Thanks!
