| Video Discription | 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.
