Other Parts Discussed in Thread: UCC28713, , PMP10200
I'm using TI WEBENCH for a DC/DC converter based on UCC28713.
The WEBENCH is limited to minimum Vin of 85Vrms / 90Vdc – is it limitation of the controller?
I do see a reference design w/ UCC28700 for ultra wide range of 25 to 525Vdc. (PMP10200)
(not supported in WEBENCH either for lower Vin than 85V)
The P/S we need:
Topology: DC/DC, Flyback, PSR (Primary Side Regulation)
Input: 42V to 420Vdc
Output 1: 24 to 28Vdc, 0.4A
Output 2: 6.5 to 8Vdc, 0.8A, this output is not mandatory
Sw. Fr: 40 to 120 kHz
Eff.: 75% min at 60% load
Transformer: should be of the shelf, similar to WE 750811647, or WE 750315315
