Ok some questions about http://threeneurons.files.wordpress.com/2011/08/mc34063_mk15cm1.gif
I plan to run the supply from 9v and need to get 180V at approx 13mA. How do I go about choosing how many of the 1ohm R's to use? Do the . 9A, 1.2A, and 1.5A labels shown designate the required input current from the supply? I completely understand the equations surrounding R3 and R4 for determining Vout. Lets say I use the default values shown, but end up with 185V requiring me to adjust R3/R4 to get my desired 180V. How would I decide which R to adjust "first"? I don't want to just coarsely adjust R3 then compensate by fine tuning via R4. It seems to me this undereducated approach would lead to the circuit getting "out of balance" between R3 and R4. Can someone help me understand how I would go about adjusting R3 and R4 *together* to get the desired Vout? Again, I do understand how to calculate Vout given a R3 and R4. What I want is to compute R3 and R4 to attain a given Vout. Thanks! -Ryan -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
