PMP41114: How to design CRPS (Common redundant power supply) ?

Part Number: PMP41114
Other Parts Discussed in Thread: PMP23338, PMP41081, UCG28826

Hi Sir,

     Qisda is going to design a CRPS. We found a CRPS product on TI’s website with the model name “PMP41114.” Could TI provide its schematics, BOM, code, etc.? Since TI Taiwan cannot support CRPS, could you please advise which TI resources or contacts we should reach out to for CRPS support?  Thanks a lot !

Best regards,

Nick CC Chen

    Hi Sir,

             I am Nick, a Power Supply Engineer from Qisda Corporation in Taiwan. Our company is currently planning to develop a CRPS (Common Redundant Power Supply), so we urgently need experienced engineers from TI to provide support. I have seen the 3.6KW CRPS Module “PMP41114” on TI’s website, which meets our requirements. Therefore, we hope TI can provide schematics, BOM, code, and other related resources. We also look forward to receiving professional support. Thank you!

    Best regards,

    Hi Nick,

    PMP41114 is combined of PFC , LLC, flyback, and ORing.

    You can separate these stages for developing:

    • PFC (including a Baby Boost), you can refer to PMP23338;
    • LLC you can refer to PMP41081;
    • The flyback, I would suggest our latest product, UCG28826;

    Hi Desheng,

          Thanks for your reply. I had checked out the information of PMP23338 and PMP41081, and had some questions as follows,

          1. Dose the schematics include all components ? Including the MCU ?

          2. Is the BOM partial or complete ?

          3. Can I buy these two boards to study from TI ?

          4. I can NOT find the source code of MCU. Can it be released to us ?

          5. PMP41081 output is just 1KW. Are there other modules that have more power output ? like 2KW, 3KW or 3.6KW ?

          In addition, can we discuss by e-mail, not at the forums ?

          Hope to receive your response soon !

    Best regards,
