SMPS powered DC motor inrush current problem
I stumbled upon a problem when connecting a DC motor to a SMPS. It's a 20W AC/DC converter with an 12V output that powers some 12V DC motors the processor and some LEDs. I needed to speed up the most ...

For calculating inrush current in a ceramic capacitor , do we need to consider the effective capacitance after derating for dc-bias effect?
Inrush current happens when capacitor is initially charged from 0V to the intended rail voltage.
What should be the effective capacitance to be considered during this charging? -Since the voltage ...

Switch mode power supply inrush current protection
I want to design a suitable PCB for my audio amplifier project.
The amplifier boards (both left and right channels) will use almost 4 amps at 24 V at full power. I want to use a switch mode based ...

Is there something called as inrush current at the output of the DC-DC regulator or LDO
I am using this LDO to step down from 14V to 5V with a maximum output load current of 150mA.
The above is the schematic of my LDO.
I want to measure the inrush current of the LDO.
But since I have an ...
