TIDM-DC-DC-BUCK: LAUNCHXL-F280049C

Part Number: TIDM-DC-DC-BUCK
Other Parts Discussed in Thread: SFRA

Tool/software:

If I'm not able to analyze the frequency response of a converter using the SFRA, how else can I achieve frequency response analysis of a digitally controlled converter? Can I hook it up the came way as an analog controlled converter and measure across a 10 ohm resistor in series with VOUT and the feedback resistors going to the ADC and get the same results? Is there a recommended way to do FRA on digitally controlled converters if I can't use the SFRA?

  • Mike,

    You can choose not to use SFRA by just not launching, connecting SFRA GUI. It will be bypassed automatically if you are not connecting it to SFRA GUI.

    Yes, you can use commercial external FRAs like BODE100/PICOSCOPE etc.

    Regards,
