Load regulation of ADM7170


I'm trying to simulate the load regulation of the ADM7170 to compare it with figure 4 of the ADM7170 user guide. However, the simulation result is showing a different result for V(out) in function of V(in), the curve in the user guide is going down with increasing input voltage when for the simulation the curve is going up with increasing input voltage. Which one is correct and why?


Best regards,

    Hi Jan,

    It's verified that temperature variation is not modeled. You may find that it’s really hard to match exactly the graph shown in the DS from testing the actual part for some parameters. There is a lot of parasitics, changes in parameters and so on, are not taken into account when temperature or frequency goes high.
