TIDM-PSFB-DCDC: Full-bridge isolated DCDC solution

LAUNCHXL-F280049C: Full-bridge isolated DCDC solution

Tool/software:

Hi,

I posted this in the reference design thread, but there was no reply, so I'm posting again in the C2000 thread. Can you give me a reply?
https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1432862/tidm-psfb-dcdc-full-bridge-isolated-dcdc-solution

Is there a full-bridge isolated DCDC solution that can be implemented under the above conditions with both the primary and secondary sides full-bridge?

- Input 40V-100V
- Output 25-50V

Probably a solution combining C2000. The purpose is to increase efficiency in the circuit.

Thanks,

Conor

    Conor,

    I did a quick search of our C2000 designs and came up with the following that match your criteria; can you let me know if any of these work?

    https://www.ti.com/tool/PMP41043   1.6-kW reference design with CCM totem pole PFC and current-mode LLC realized by C2000 and GaN

    https://www.ti.com/tool/TIDA-010062 1-kW, 80+ titanium, GaN CCM totem pole bridgeless PFC and half-bridge LLC with LFU reference design

    Best,

    Hi Matthew,

    I apologize for the misunderstanding.

    The solution we are looking for is a PSFB (with secondary full bridge). I would appreciate some advice.

    Thanks,

    Conor

    We dont have peak current mode control PSFB with FB in the secondary. We have center-tapped secondary in this category. See TIDM-2000 for this.

    But for voltage mode PSFB with FB secondary we have TIDM-2002.

    Now, none of these designs will match your input output power stage specs. You have to design your power stage to meet your specs. Then you can take one of this s/w (perhaps TIDM-2002 s/w since you need FB secondary) and modify the parameters accordingly to meet your power stage specs.
