Hello Sir/Mam, Kindly update me with the following. I am looking to design output 400VDC/50mA. The input to the supply is universal . kindly suggets could we use Any PI device, If yes, which device & if not, why Not?

I am designing a universal AC input 21V 3A output using a TOP247Y. This is the first time I design such a switching power supply and I'm not so sure how to design the Clamp and Reset circuitry for that power. I went thru the AN31 but I'm still unable
