How to Select a Soft-Start Solution for Switching Power Supply Inrush Current
A power supply that runs comfortably at 3 A can still demand 20 A or more for a few milliseconds when it is connected. That short event is enough to trip an upstream adapter, open a fuse, pit a connector, pull down a shared DC bus, or reset nearby controllers. Repeated starts also add electrical and thermal stress to rectifiers, MOSFETs, capacitors, and PCB traces.
