I am looking for some direction in creating a variable +/- 400V @ 10uA max output controller. Currently I have a flyback solution designed that can do it, but there are issues with the feed back voltage resolution and the way the microcontroller is managing the output voltage. It would be nice if I can find a controller that is able to handle the regulation for me with <1mV of output ripple for the purpose of this product.
Here are the specs:
Variable +/- 400V output
output voltage ripple: < 1mV
output supply current: <=12uA
Here is one of our reference designs (http://www.ti.com/tool/PMP2971) for 370V @ 1.75A.
Have you looked at our High Voltage Motor Control Page?
There are a couple of reference designs and app notes that might be a good platform. Hope this helps.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
