Other Parts Discussed in Thread: LMG3410-HB-EVM
Serkan-san,
I tried your proposal.
I just only changed Si MOSFET to LMG3410-HB-EVM according to your proposal.
But did not work.
RVCC does not up to 12V.
Do you have any idea?
Any check point?

Ben-san,
Today it works very well. I have got one idea of internal chane of LMG3410-HB-EVM (my EVM is old version)
1st AC in, next DC230v in, and then gradually up the DC input voltage.
I have got best efficiency curve.
Before this change, burst in point was changed to from 40%of full load, and changed to SR.
If someone give me new LMG3410-HB-EVM, I will write the change procedure. Because my EVM and user's guide cct.dia are different.
HS 385V on/ off switching waveform is pretty good and it looks like very low voltage driver output waveform.
Thank you.
Ben-san,
I need new LMG3410-HB-EVM.
Because I have old LMG3410-HB-EVM.
It looks like very smaller cap. on LMG3410 12v input.
New LMG3410-HB-EVM's 12V line cap is very heavy so that Rvcc 12v will be shut down.
Especially focusing High-side boot-strap cap.
If I do not check this point, I can not show you the modification manual.
Can you ask the EVM to Masoud-san?
Sometime I was asking about GaN by email.
Thank you.
