Modern day 723 and 78xx for new design

<< < (6/6)

battmyrne216:
 found the manual for mine. Which contains the 723 chips.

iMo:
Interesting current limit wiring in the XP-581 schematics..

coromonadalix:
Nothing special, a 4 voltages outputs psu with no current adjustment ??? and one variable output voltage.


The SG1532/SG2532/SG3532  may be more modern,  BUT they start at 4.5vdc min up to 50vdc output, once again ou have to negate the output voltage to drop it to zero

You have some "google" projects with 723 designs who go up to 70vdc and more

Wolfgang:
... you can "float" your 723 if you need more than 40V out. I've seen HV supplies (1kV) with floating 723s (having a 12V float supply).
