Hello,

I searched the TI reference design library and found this PMP7167 off line flyback that is close to your design needs using the UCC28610.

can u suggested one ic that have facility as a input AC=115 V ,400 Hz or DC=28 V one at a time as a input and out as 5 V DC and 1 A

Hello,

400 Hz is the line frequency generally air craft or ship power. So you just need a a bridge rectifier which that design has.

I marked up the schematic to show the AC to DC converter using a bridge rectifier and storage capacitance. Then you step down the DC voltage to 28V in a DC to DC flyback converter. I believe the control IC in this design is a UCC28610 and this reference design would work in your application for 50 W.

On your other post I had recommended using the UCC28711 or UCC28704 and recommended to reference designs as well for the 5 W application.
