Hello,
Recently we have been working on module PMP40328. At low input voltage range (90V~150V), the output voltage is stable at 9.04V. However, at input voltage>200V, the output voltage is unstable (which kept changing from 7.64~9.13V). Why the input voltage range affects the stability of Vout? Or is there any problem we should check on our PMP40328?
Thank you for answering the question.
Sincerely,
Chiao
