Part Number: TPS62136
Hello,
I have simulated the attached schematic using your TPS62136 with PSpice. If the feedback voltage (green) is above 0.5V, it does not follow the tracking voltage (red) anymore the slope differs.
In conclusion the tracking is not precise enough for a ratiometric ramping scenario (cyan, pink).
Is this behaviour due to the simulation model or also seen in real world ? Especcially if considering the ramping in slva470a.pdf figure 9.
Best regards
Stefan
