What is Inrush Current and How to Limit it?
Inrush current is the maximum current drawn by an electrical circuit at the time it''s turned ON appears for the few cycles of input waveform. The value of the inrush current is much higher than the steady-state current of …
Managing Inrush Current (Rev. A)
TPS22902B Inrush Current The peak inrush current measured is 392 mA. This is well below the 600 mA design requirement and much lower than the 1.6 A seen in Figure 3 without any load …
How to Calculate Inrush Current
Capacitors draw inrush current as they charge up to the supply voltage. The magnitude of the inrush current depends on the capacitance value and the series resistance in the circuit. Capacitance Value: Larger …
