We will discuss how to build a Buck Converter with single LOW Side N-Channel-MOSFET. We will also look at how we can tune the circuit easily and what mistakes to avoid when building buck converter.

Supplies

1x n-channel MOSFET (IXTQ52N30P)

1x Diode (30ETH06)

1x Inductor 40uH (although the bigger the better)

1x Output Capacitors 180uF (also, more the better)

1x Input Capacitor 3uF

In this video, we will discuss how to build a Buck Converter with single LOW Side N-Channel-MOSFET. We will also look at how we can tune the circuit easily and what mistakes to avoid when building buck converter. I gave some tips in the video on how to avoid inductor saturation, and how to keep buck converter operating in CCM (Continuous conduction mode)

In this video I will be stress testing my buck converter circuit at 160V with a toaster oven and also share some upgrades I made to the circuit.
