Hot Plug-In In-Rush Current Limiting Circuits for PT3100/4100/3320 DC-DC Convert (Rev. A)
Texas InstrumentsIn-rush current is the initial current that flows to the converter’s input de-coupling capacitor(s) when the host board assembly is connected to an active input power source. The magnitude of the in-rush current is high and can induce arcing, transients, and erosion of the connector. Limiting the in-rush current allows the host board assembly to be safely plugged into a live system backplane connector, such as those powered from a -48V central office power supply.
