All depends on the output current - what's it for?=20 =46or low current apps, you might just be able to get this high with a simple inductor based flyback converter, but inductor selection will be critical, although probably still off-the-shelf. If you need it regulated, Maxim's MAX771 can control an external HV MOSFET - I've used this to get 200V at a few mA in the past. You need to run the MAX771 itself from a seperate 5V supply.=20 No problem at all with a transformer-type inductor , but you may need to custom wind the transformer. You may find a suitable off-the-shelf inductor designed for small xenon flasher applications. If the current is extremely low (microamps), an EL driver IC driving a few stages of Cockroft-Walton multiplier may also do the job. -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
