Step Up 3 to 65V

I am writing to you in order to get information about your products. We are interested in building a voltage source powered by 3 to 5 VDC that generates an output of 20 mA and 65 V, or higher. We have performed a simulation with the step-up DC / DC converter LT3482, however the current generated is insufficient. I would like to know if you can recommend us another of your products, or some way to build the power supply with the aforementioned requirements. Thank you for your assistance,  Sincerely, Mr Jose Intelesano, P.Eng.

    Hello Mr. Intelesano,

    You are correct in that LT3482 will not deliver the current you need.

    If your converter "must" operate from a minimum input source of 3V, it will be difficult to achieve a simple boost approach. For a 20mA load I would recommend the LT8362 in Boost configuration, with an added doubling stage.

    Please see attached illustration for doubling stage.

    If you require more than 20mA of load current, please be more specific, since the approach recommended might not suffice. 

    Best Regards
