Hello,

Thanks for reaching out. You might want to use the LM5156 or LM5157 for example in Flyback configuration or as a boost + charge pump on the switch node ( please refer to the applications section of the datasheet for further examples). Let us know if you need further help.

Kind regards,

Can I see the application note of boost+charge pump?
I can't find it, so I'm asking for your help.

Thanks
