Part Number: LM5170EVM-BIDIR

Hello TI team

I have one confusion for ISETA signal, the user guide says that apply an analog voltage between 0 to 1.5V at ISETA pin. So do I need an external supply with DAC or what should I do for that supply? First I want to use on-board outer voltage loop control. so in this case what should I select?


  • Hi Salman,

    You do not need an external supply if you are using the EVM in voltage mode. The outer voltage loop would adjust ISETA.

    An external supply will be needed if you want to program the output current.

    Please do not ask same problem twice which would waste our time.

    Best Regards,
