Hello Fujihara-san,
My thought is that the ripple injection is interfering with the feedback voltage. However, I do not expect the feedback voltage to move 2.6V under normal operation.
You can see PMP15005 is an exmaple of an inverting flybuck design…

What is the best Flybuck isolated switching regulator to use with the following requirements:
1) Input voltage : 28V - 12V 2) Output voltage: 7.5V 3) Output current…
Hello,
When I open the datasheet, I see the output current is rated to 2A.
For example flybuck designs, there are multiple reference designs on the Tools Tab, including: www.ti.com/.../PMP15005. You can also see the EVM with the flybuck configuaration…
