TPS40210: -15V to -50V/0.2A solution

Hello Haiwen,

Thanks for using the e2e forum.
It is possible to use a boost controller like TPS40210 or LM5156 for this.
A reference design is given here: https://www.ti.com/tool/PMP9624

There are already some questions on this design within the e2e forum for additional explanations:

Please let me know if there are any additional questions.

Best regards,
Niklas
