I am using AC power supply 230V to power On the driver board using LNK419EG, I measure the current from primary transformer to Dpin. The spike current seems very high until cutoff by over current protection? Some pulse is missing as seen from oscilloscope.
The output current is high as 1.2A. I fine tune R15 value. What is the value component I should choose.
Please see attached photo and schematic.
