  • RE: LM5022: Isolated Flyback - Additional Output on Primary Side

    Resolved
    Hi Jan, Unfortunately, I do not have a recommended solution for a transformer. In order to utilize that specific transformer, you would need to connect multiple winding together to generate the appropriate turns ratio. However, what I can do for you is…

  • RE: LM2587: Designing dual output flyback circuit.

    Hi Robert, LM2587 minimum current limit value is 5A, which is not big enough for this application. You can take a look at the reference design: http://www.ti.com/tool/PMP20551

  • RE: TPS23756: PoE controller (TPS2373/TPS23756) for 51W with 16 to 57V input?

    Hi A,. I recommend using the TPS23756 for the 12V/2.5A solution since this is a Type 2 application. I recommend using the same power stage as PMP20551 except using the TPS23756 PWM Controller. For the Type 3 24V/2A, I recommend the TPS2373-3. Unfortunately…
