Other Parts Discussed in Thread: SN6501, SN6505A

I would like to use the transformer from Wurth Elektronik at the link below for my application.

If possible, please show me the smallest footprint Isolated DC-DC Converter that can convert 5V or higher to 5V.

The SN6501 is great but the center-tap transformer is needed and the size of the transformer did not fit in my application.

Thank you in advance.

    Hi Phuong, and welcome to the E2E forums!

    TI's two isolated transformer driver devices, the SN6501 and SN6505, are the same dimensions: 3mm x 3.05mm max with the main package difference being their number of pins.

    Both devices can drive transformers in 5V:5V and 5V:5V+ configurations, however a center tap is required at least on the transformer's primary side for the system to function. Coupled inductors alone will not work.

    Your contact at Wurth Elektronik may suggest a compact center-tapped transformer which meets your system needs and pairs with the SN6501 or SN6505A/B. Have you already chosen which of these devices to use? The SN6505A and B versions are more capable than the SN6501 in terms of power output and features. Please reply if you would like for me to elaborate.


    Thank you for using TI parts.


    Respectfully,
    Manuel Chavez

    Thank you Manuel Chavez.
    I am contacting Wurth Elektronik and hopefully they would consider building a small canter tap transformer for me.
    Thank you again for your support.
