3 Phase SMPS for PowerLine Modem
Input AC operating range : (ThreePhase 4 Wire System)
Phase to Phase ( R-Y or Y-B or B-R ) : 430V
Phase to neutral ( R-N or Y-N or B-N ) : 230V
SMPS IC Switching frequency should not be in range of 60KHz ~ 90 KHz and 110KHz ~ 150KHz.
Output1 : 16V/ 1.2A
Output2 : 5V/ 2A
All o/p are with ref to common gnd
Could you please help me out for the design

Could we use below PI device..
TOP221 ~ 227 Series. Which is switching frequency is 90 ~ 110 Khz.
or TNY377GN-TL

TOP221-TOP227 series is a good choice for your switchng frequency requirement.
Thanks a lot for using PI part.

I can not find any similar exisiting reference board/report. Could you PLS contact with local FAE? Maybe they can help you.
Thanks
Will these TOP devices are active or obsolete parts.

TOP22X are old parts, but they are active right now.

Thank you

It is impossible for PI part to avoid the 60kHZ-90KHz AND 110kHz -150kHz.
Sorry about that.
