Hi,

Do you have any following reference design?

input : DC12V-24V
output : 300V / 3A (about/peak for Igniter)

isolation : Flayback or etc.

Regrds,

Hi PAN-M,

Unfortunately, there is no reference design in this spec for you since it is not a common spec.

I think Push-Pull or Full-bridge converter is a good choice for this spec, but maybe it has a challenge on transformer design due to larger primary current.

Regards,

Teng

Teng,

Thank you for quickly response.
I do not understand igniter well.
This peak current may be around 1A to 3A, but this only several ms.
I think that I should know the design example by this application.

Thanks,
PAN-M

Hi PAN-M,

Sorry that i haven't the reference design with this spec, but I recommend full bridge topology for you.

I am closing this thread.

Thanks,

Teng
