  • PMP40328: Unstable Vout (7.64~9.13V) at Vin>200V

    TI Thinks Resolved
    Part Number: PMP40328 Hello, Recently we have been working on module PMP40328. At low input voltage range (90V~150V), the output voltage is stable at 9.04V. However, at input voltage>200V, the output voltage is unstable (which kept changing from 7.64…

  • RE: PMP40328: Cannot find any info on transformer used in design

    Hi, Dan, This transformer is designed by Wurth Elektronik. You can contact them for the design details. Maybe it is not public in Wurth Elektronik official website.

    Dear Hiroshi, Thanks for interested in TI's solution. I will suggest you use UCC27712 as gate drive. Here is the reference design: www.ti.com/.../pmp40328 Best Regards Kevin

  • RE: UCC28780: Can UCC28780 used other switch rather than GaN?

    Dear Sir, UCC28780 is suitable for Si and GaN devices, just change the SET pin's configuration. For Si, connect SET pin to high. Here is a design base on Si with UCC28780. www.ti.com/.../pmp40328 Don't forget to promote UCC24612 SR controller…

  • RE: LM5114: lM5114

    Resolved
    Hi Robin, thanks for posting on LM5114 and HV GaN! it looks like your attachment was lost, can you please re-post it? PMP40328 uses UCC27712, a 600V gate driver, which would not fit your bus voltage however have you checked out the isolated GaN/MOSFET…
