I think about the multi-output by flayback.
(DC3.3V/450mA, DC15V/10mA, DC-15V/10mA, DC24V/30mA)
Our customer made the following transformer.
inductance : 700uH
Turn ratio (24V output) : 2.69:1
Turn ratio (12V output) : 5.38:1
Turn ratio (3.3V output) : 17.5:1
Feedback is 3.3V.
I want to get good cross regulation of 12V and 24V, what kind of method is there?
I am understood that the output voltage changes to some extent because Duty changes.
