UCC28710: PMP9041 questions

Part Number: UCC28710

Tool/software:

Hi All,

  Good to see you from online.

  1. When saw PMP9041 reference test report, it looks like the output voltage value is 25.91V under Io=0A Vin 229.8Vac condition. Is there any action that can help control the output value within the range of 25.2Vdc to 22.8Vdc (24V+/-5%) across load/line regulation?

  2. How is the work frequency value set for this transformer design?

  3. How is the Vds peak value under full load at 265Vac condition?

  4. Could you please to test a 1A to 1.7A transient under 1115Vac/60Hz &230Vac/50Hz for evaluation?

  5. How is the maximum winding temperature temperature rise &core & Bobbin in actual test?  

  6. Has the PMP9041 demo been run RE compliance test? Thanks for any input.

BR,

Xiaobing (Eric)
