We have a question for this IC when we use two output feedback control.
We can't get stable operation. one voltage is 12Vdc and the other is 160Vdc. 12V is about 110W and 160V is about 1.2A.
12V need to be control with in 4%, and 300V is input voltage for boost circuit.
The power is about 340W max and 300W for typical.
Can you help give us some advise for parameters.
And the other we face burst mode problem, the problem is we can't reduce power loading level when burst mode off.
That will case acoustic problem in low power. Please also give some suggestion.
