What about reverse bias protection on the LT3080, does the design need it? Dave does a quick test to find out what happens. Will it smoke?

Dave goes through the final base schematic for his Open Hardware lab power supply design. Schematic is here: http://eevblog.com/uploads/uSupplyBenchRevA.pdf

2011 was a big year for the blog… Sorry for the crap video quality, Youtube screwed up the video stabilisation feature and I can’t revert back!

Dave, Phil, and Rog battle Murphy to find an elusive short on their ArduCopter ArduPilot IMU (OilPan) board before they can get their CanyonCopter in the air for its first test flight. Or, how to trace down a short on your power rail.

Dave reviews the 4th Generation Amazon Kindle Touch Ebook Reader. See the previous Kindle Non-Touch Review here:

The 4th installment in the lab power supply design series. This time Dave shows you how to control the supply with a Pulse Width Modulation (PWM) signal, and chose the correct filter values.

Part 3 of the lab power supply design. This time the prototype build on a breadboard and some basic measurements, checks, and playing around.

Dave demonstrates a little trap with the “High Resolution” mode on modern digital oscilloscopes like the Agilent 3000X series.

PART 1 is HERE: http://www.youtube.com/watch?v=CIGjActDeoM Part 2 of Dave’s constant current linear regulated lab power supply design. An in-depth look at the LT3080 datasheet, the LM334 current source, and a few more circuit tweaks before it’s ready to build in the next episode to see if it works! And thanks to John from LT who pointed out this video from LT about the LT3080, given by Bob Dobkin himself, the LT CTO and designer of the LM317! http://video.linear.com/11

Dave shows you how to design a simple constant current and constant voltage lab power supply that can be either software (PIC/AVR et.al microcontroller) or traditional pot controlled. Starting with the venerable LM317, and ending up with an LT3080 solution, and the some thought processes that go into it all. Part 1 is the conceptual design.
