Hi Liv
Que! >>
I do not understand what interest to do simple design today...One thing i learnt is this, do not make things more complex than necessary!
CPU controled Power Supply's, almost never i use them for developement.
I use most the Dutch DELTA Linear power supply's (some 40 years old), and multiple power supplies of HP/Agilent.
And multiple power supplies of my own design.
All linear, no switchers and no CPU control, give me two multiturn potmeters for U and i, and i'am happy
All are analog, and there is one exception, and that is the "DELTA ES-30-5", a nice low noise switcher.
A cpu controled Power Supply can be usefull, i know, but fore development only sometimes necessary. (i know, i know there are exceptions)
These characteristics I expect from a Power SupplySimple to use, all my attention should go to test the circuit and not with the operation of the Power Supply.
The power supply may not have power On or Power Off aberrations.
The power supply must have a mute without On/Off aberrations.
The power supply must be kind to itself and the load.
Low Noise under all conditions <0.1mV 200Khz BW.
Fast acting no oscilation current limiting.
I can make the list longer, but i think you understand my point :-)
Just 2 cent's of low noise remaks
Kind regarts,
