Robert White Posted April 12, 2023 Share Posted April 12, 2023 I want to run the Analog Discovery Pro 3000 off of a battery pack. Input is 19V which is an awkward value. I can't find any acceptable range in the documentation. 18-24V? 15-30V? What is ok? Thanks! Link to comment Share on other sites More sharing options...

0 Robert White Posted April 12, 2023 Author Share Posted April 12, 2023 Thanks @attila. Not a very wide range ... I'll try to find something ... attila 1 Link to comment Share on other sites More sharing options...
0 Robert White Posted April 12, 2023 Author Share Posted April 12, 2023 Not a lot of DC DC converter options that output 19V ... will it die if I feed it 24V ... anyone know of a DC DC converter that puts out 19V? I found this thing but its kind of big (3 lbs, 30 cm long) https://www.powerstream.com/dc-buck-boost.htm Couldn't find anything on Mouser or Digikey Link to comment Share on other sites More sharing options...
0 attila Posted April 13, 2023 Share Posted April 13, 2023 Hi @Robert White 19V is common for laptop supplies. 24V will not work since the device has an input protection with tight threshold around 19V (about +/-0.8V). This IC is also used as the main digital on/off switch. Link to comment Share on other sites More sharing options...
0 Robert White Posted May 2, 2023 Author Share Posted May 2, 2023 Hmm. Thanks for the answers. I'm feeling stuck. 19V adapters for laptop use AC power from the wall ... 110/220Vac ... but I'll be on a remote platform with only DC power available at 28V or something like that ... any ideas anyone? Need a box to convert 28-34V-ish DC power to 19V +/-0.8V ... Link to comment Share on other sites More sharing options...
0 Robert White Posted May 2, 2023 Author Share Posted May 2, 2023 I think I found something. https://www.bixpower.com/product-p/dc36t19v-6a.htm I'll give it a try! Link to comment Share on other sites More sharing options...
