- I have a need to obtain 600VDC at about 150-200mA from an
- 800VDC supply. It need not be exceptionally well regulated
- voltage-wise, but does anyone have a simple solution?
- (not as simple as a resistive voltage divider however!)
-
- Pointers to databook circuits or devices greatly appreciated.

- Thank you
How about:
/ /
------800V------>|------>|--------/\/\/-----600v----<load>----
/ / R |
100V zener 100V (I limit) <GND>
You may be able to find one 200V zener, I'm not sure, though. Choose
zeners of sufficient current capability for your application.
