The MC 34063A (DC to DC up/down) Buck Converter Chip from Texas Instruments tested (schem/demo)

Please read the description first. Testing the DC to DC (up-down voltage) Buck converter of Texas Instruments (T.I). Its name is MC 34063 A. When you go to the Texas Instruments website now (15 Oct. 2024) they tell that there is a new version of this chip available, with (as far as I could see) other pin connections. That (of course) in fact does not matter (changed pin connections) and does not bring down all the good properties of this “first” MC 34063A Chip, being a DC to DC converter. The chip has very good properties, giving out (in this application, showed in the video) exactly 6 Volt (always) with an input Voltage of 25 Volt. With different loads, my test was going to max. 30 mA. At first not tested on higher output currents by the way, you can do that, of course. NB: today also tested, afterwards, with a small lamp, making a 108 mA output current, more in this textbox. In this case (demo/video) it was used as a Step-Down DC-DC converter. Input 25 Volt, output exactly 6 Volt, all the way. More info about that output Voltage is in the video. The Chip can also be used as a Step-Up DC-DC converter, converting (say) 12 Volt to a higher Voltage. Not showed here, but surely on the Texas Instruments website. That video (STEP UP the DC to DC voltage) is here (16 Oct. 2024)    • The MC 34063 A tested as STEP UP conv...   Thus everything about its good use is told in the datasheet on the Texas Instruments website, showed in the video. Thus both stepping up and stepping down via this DC to DC converter, where an oscillator plays an important role, to do that with minimum losses. Thus with as less heat/loss as possible inside that (tiny) Chip. So a very good idea from the T.I. engineers. It only got a little bit warm (very tiny) when converting 25 Volt to 6 Volt at 30 mA, and that is a very good result. But (also important) when you load the circuit with a 6 Volt 0,6 Watt incandescent lamp the voltage drops down to 4 Volt and the Chip gets very hot. Tested today, after the first experiments. I found 108 mA at 4 Volt in that case. I only tested it for a few seconds, trying not to burn out that chip. It was not on a heatsink, by the way, it was on free air (showed in the video). Thus perhaps on a cooling plate this chip can handle that projected output current (in reality, that is only my idea, max. approx 300 mA). Ohms law and the Watt law are always here, even with the most sophisticated chips. That is physics, working in practice.... Safe value in this case: a 40 mA output current max. when the chip is not on a heatsink. My You Tube channel trailer is here:    • Radiofun232 on YouTube (updated monthly)   When you search, search always “NEWEST FIRST” to get the right overview. You can also search via the “looking glass” on my Channel trailer via keywords like ”audio”, “radio”, “amplifier”, “filter”, “Shortwave”, “transistor”, “FET”, “oscillator”, “generator”, “switch”, “schmitt trigger” etc; so the electronic subject you are interested in. My books about electronics & analog radio technology are available via the website of "LULU”, search for author “Ko Tilman” there. https://www.lulu.com/search?adult_aud... I keep all my YT videos constant actual, so the original video’s with the most recent information are always on YouTube. Search there, and avoid my circuits that are republished, re-arranged, re-edited on other websites, giving not probable re-wiring, etc. Some persons try to find gold via my circuits. I take distance from all these fake claims. I cannot help that these things happen. Upload 15 October 2024. My (always) advice: do your own experiments, also here. Make it and test it. It is the reality about understanding electronics, getting idea’s about schematics everywhere published on the www. How they can work/could work. So that you can get a sure idea about how and when such a published electronic circuit on the www. can work or will not work or needs adaptations. The www is, in certain terms, a jungle when we are talking about reliable and reproducable electronic circuits. 15 October 2024.
