Should I limit inrush current of this MOSFET buck regulator?
I am building a digitally controlled constant current switching power supply. This circuit will deliver no more than 105 Watts at around 20V from an AC-DC DIN rail SMPS of 250W.
You can see and ...

use of capacitors and inductors in buck converter [closed]
For stepping down voltages, why can't we use a simple resistive circuit and the voltage division rule for the output? Why do we use a buck converter instead? What role do a capacitor and an inductor ...

Selecting capacitor and inductor for adjustable buck converter
I'm trying to understand how to choose the right inductor for a buck converter that can produce different output voltages.
When using an LM2596 I can add a potentiometer into feedback loop to produce ...

Buck converter without inductor in a NiMH charger (Zilog AN0259 application note)
After doing some reading online, it seems that you can't really build a step-down converter with only a filtering capacitor and without an inductor, because the losses occuring during charging of the ...

Buck Converter Capacitor and Inductor Characteristics
I'm trying to make a buck converter with this mickey-mouse MC34063A chip that will step-down +5V to +3V3 up to 500 milliamps. I've gone through the calculations by hand and validated them with an ...

Current step to LC circuit
An inductor is a device which adjusts its voltage to keep the same current flowing through. However, the current exponentially decays when there is no source any more. Similarly, a capacitor is a ...
