Inrush current during power supply startup can disrupt adjacent components and degrade system reliability. Relying on steady-state current measurements won't show you the peak transient.
This video demonstrates a reliable workflow for capturing startup current spikes:
Utilizing a current clamp to monitor the power rail
Setting up a single trigger event above the steady-state noise floor to capture the transient peak
Using measurement rulers to analyze the amplitude and decay of the inrush current
How do you typically characterize transient startup events in your power designs?
