Hello all,
I know it is an oft repeated topic, But I'm in need of a PIC based Digital power Supply - PIC16F84 or PIC16F877 based. It should have a EEPROM memory (internal or external) so that the power supply settings remain the same after it is shutdown and restarted. Also, the source code should be in english. Does anyone know any PSU matching these specs ???
Thanks in advance.
 

Hi

Here are some links at elektroda, as you mentioned the topic is already discussed a numerous times here, please use Search.

There are some designs published in magazines, but you can check yourself at elektor and EPE. Circuit Cellar have published an article about a PSU around the 8051(?). I do not remember which issues but if yo have problems finding them tell and someone will help you.

I am not sure they adapt to your specifications but they can always be a help.
