MP6005A Flyback start-up and stability

DC-DC Power Converters
#1

Hello MPS Team,

I use the MP6005 in a isolated flyback supply with 48V input to 900 V output voltage for about 30W.
There are problems during start-up I think due to the overload protection.
Is there a possibility to implement soft-start?
Or do you have suggestions for enhanced stability?

Best regards,
Martin

Hello Bosch,

Is it possible for you share what you are seeing on the input/output?

The MP6005 already has an internal soft start of 4.7ms.
