Dual ±200V output power solution

HI, team：

    My customer is finding dual ±200V or ±100V  without  transformer power solution， could you give some suggestions?

    Input 12V, output ±200V or ±100V， 0.1A is enough. 

    Hope to get your reply!

    Hi Hailey,

    Any PWM controller can be used to make a boost or inverting boost converter. See the following application note (SNVA856B) on how this is done. The UCC28C50 might be a good solution to make this happen. Without a transformer-based solution, you would need two controllers. One for the boost and another for the inverting boost. 

    I hope this answers your question.
