EEVblog #105 – Electronics Thermal Heatsink Design Tutorial

A follow on from some of the recent blogs that have involved basic thermal heatsink calculation. This time around Dave takes you though the basic theory of thermal design and how heatsink calculations work. Then there are some real world temperature measurements to see how close to the theory we get.

How do you read a heatsink thermal response graph? What is emissivity? It’s all here in thermal design 101.

EEVblog #95 – Linear Regulators, Closed Loops, Simulations, & Brand Shenanigans

A bit of a follow-on from the linear regular episode. Dave dances with a simple linear closed loop circuit he built, and bodges it up in LTspice to get a remarkably consistent result.
Not really a tutorial, just a few random tidbits.

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

Just how different are linear, LDO and switching buck voltage regulators? 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!

EEVblog #87 – Let’s hop on the Electronics Design Merry-Go-Round

Dave demonstrates how much fussing around can be involved in selecting just a couple of cost optimised parts for a new design, using Digikey, Mouser, FindChips, Octopart and Atmel websites.
