For one of our application we require AC to DC converter and DC to DC converter which gives 2 selectable outputs. Our specifications is
1) AC INPUT:- 160V to 260V AC supply
DC Output 1 :- 32V with 5A current
DC output 2 :- 20V with 5A current.
Dc o/p 1 or dc o/p2 are selectable
2)DC INPUT:- 22V to 40V DC supply
DC Output 1 :- 32V with 5A current
DC output 2 :- 20V with 5A current.
Dc o/p 1 or dc o/p2 are selectable
We request you to advice how to proceed. Looking out for Minimum BOM count.
Hi Jayaprakash,
Please find the devices that can be used in application below.
Design 1st stage AC-DC for Vin = 160 to 260, Vout = 32, Iout = 10, Isolated (UCC28634DR may not work as 320W may exceed device limits .
Resonant Flyback UCC28600, LLC controller UCC256403 can be used.

Design 1st stage DC-DC for Vin = 22 to 40, Vout = 32, Iout = 10, Non-Isolated LM5176-Q1 can be used.

Design 2nd stage for Vin = 32, Vout = 20, Iout = 5, Non Isolated. (LM22677 will not work as max Vout for this device is 5V. LMR14050S or LM25088 may be good alternative considering lower BOM count ).
