TPS51116: TPS51116

Good morning, due to a layout error, the regulator is causing interference on my VREF. Can you suggest a way to slow down the dv/dt?

    Hi Angelo,

    Can you provide a little more information? Do you mean the switching regulator output VDDQ is interfering with your VTTREF somehow? Is it the switching noise or just the initial power up?

    There's no built-in slew rate control so I imagine adding capacitance would be the only way to change dv/dt but I'm not sure if you mean the ramp up of an output or the switching node before the inductor.

    Regards,

    James
