    Part Number: PMP8583 Other Parts Discussed in Thread: UCC28910 , UCC28910FBEVM-526 Dear, Sir. I am facing a quite conservative customer that he dont want to change to new device. However, he is interested in PMP8583 Reference Design, so mentioning that…

  • RE: UCC28910: Transformer for 13V output

    Victor I am assuming the design is based off of UCC28910FBEVM-526. The total VDD capacitance on this EVM is 10.1uF. Increasing it by 4x will extend the startup time drastically. I recommend verifying the following parts of their design with the excel…

  • UCC28910: New Transformer design & component values

    TI Thinks Resolved
    Part Number: UCC28910 Hong Huang, We are working on a new design of a transformer for use with the UCC28910. This transformer schematic is below, whereas termination 1&4 will be connected to primary side GND (high voltage ground), just like the UCC28910FBEVM…
