  Part Number: PMP8677 HI I'm TSA of Micro-star. MSI is looking for fly-back solution that output is 12V, and PMP8677 is fit to their requirement. However, I can't found this EVM board in internal system. Is it available?

  PMP8677 does not have PFC regulator in it, so the voltage after the diode bridge does not discharge to 0V every line cycle.

  Hi Chandan, For the 36V output, I would suggest a PFC + LLC. You can look at UCC28056 or UCC28180 for the PFC controller and UCC256402 for the LLC. For 45W, a flyback is appropriate. PMP22087 might be a good reference to look at. For the 12V, you could…

  Barend C15 is used to filter out noise on this pin. Our documentation has an error and incorrectly shows a resistance for this capacitor value. I've reached out to the designer of PMP8677 to correct this. The example design in the LM5023 datasheet…
