We've been trying Linkswitch XT2 900V ICs and for transformer design and initial sample configuration we used suggested PIXI design for transformer.
Problem is that with LNK3694G IC it does not seem to be reliable or accurate.
There are several inconsistencies:
In spreadsheet suggested primary is 36AWG but in transformer design it changes to 35AWG
Suggested bias turns results in less than 12V calculated bias voltage. In our test board testing after diode output voltage for bias is well over 20V when adjusted in PIXI to be just above 12V.
Is there a fix planned for this problem?
And should be bias turns used calculated or adjusted to be over 12V?
