1. Have 3 phase ac input with neutral, where each phase voltage goes from, 85V-600Vacrms
2. Need output at 5V/500mA
3. I was checking it: https://www.st.com/resource/en/appl...cations-with-viper12a-stmicroelectronics.pdf
its page 8 has this, that is to make dc from 3 phase
I checked ST/s VIPER267K, which has BVDSS of 1050Vdc .
But at full 600V each phase, the output dc after diode, can go upto 1100V (simulated on multisim)
4. https://training.ti.com/sites/default/files/docs/Very_high_Voltage_bias_BK_13-Sept_complete.pdf
page 22 shows external fet operation, but again limited to 1200V, very close, so cant use
5. Anyone have experience in this low power application where size/size constraints? Any reference design?
