Flyback PSU
Hi,
I have very limited SMPS experience but am frantically trying to put together a 24V to 5V Flyback convertor running at 1MHz. Its all running fine except there is about 2V pk-pk ripple on the output. If I scope the transformer input before the rectifier diode the waveform is nice ant flay when high, but sort of a dying away sinewave when not high and that appears to be where the ripple is coming from. The transformer input looks fine. I suspect my transformer. Im afraid it was more of a guess than precision engineering.
Has any one got any thought on what might be going wrong here.?
