Hey gents, I have this problem of converting 240V AC to 28V DC. I know the traditional way of using step down transformer then rectifier bridge then voltage regulator and what not. However the transformer is required to be mounted on the PCB (rating at 100VA, 3A --> too big) so this traditional method obviously doesn't work. Other alternative I could think of is a flyback converter. What are your thought on this? Any other topology that could reduce the size of the transformer? Thanks heaps!
