EEVblog #90 - Linear and LDO regulators and Switch Mode Power Supply Tutorial

Just how different are linear, LDO and switching buck voltage regulators? I'm glad you asked! You might be surprised... It's tutorial time. NOTE: There are many different methods of SMPS control, this is just one of the simple ones, go investigate!

A Buck Converter Too Far - DC Power Transmission Project Fail

I found a neat-looking buck converter on eBay with a 60V maximum input voltage and a 30V maximum output voltage. The trimmer potentiometer let me take the output voltage up to 40V with predictable results.

In this video I'm comparing in practice a buck converter with LM7805 linear voltage regulator. Two driver boards from old hard drives are used as a dummy load to check efficiency and temperature of the buck converter and linear voltage regulator. I'm presenting pros and cons of both devices.
There are 2 mistakes in my calculations:
1. 5:02 - 5:08 - correct calculations should be: (12V - 5V) x 0.42A = 2.94W
2. 5:17 - 5:23 - correct calculations should be: (12V - 5V) x 0.22A = 1.54W
I double checked everything, but I should have triple checked. I'm sorry for my mistake.
