  • RE: LM26420-Q1: Calculations and design of my power circuit and device request for the Webench simulator

    Hi Francisco, Just a gentle reminder. Can you share the initial PCB layout/connection and with the improve signal quality (GND as close to the DAP pins) to better understand the difference between the two layouts? Best regards, Excel

  • RE: WEBENCH-POWER-DESIGNER: How to add a specific core / coilFormer to webench power designer

    Still no response from product expert. Design questions such as: - For the design for cost optimization of the simulation design above (no Optocoupler between Sec and Primary), which is the secondary side voltage regulation? How behaves the load regulation…

  • PMP7991: Transformer choice 7508112328 does not match WEBENCH design based on same circuit characteristics.

    TI Thinks Resolved
    Part Number: PMP7991 Hello, the reference design PMP7991 shows the development board using the 7508112328 transformer as part of fly-back conversion. However, your WEBENCH tool output circuit design based on same circuit characteristics do match transformer…
