OCP2 fault is coming , even there is no load. I am confirming the OCP2 fault, by seeing the waveform at Fault pin.
We are using this IC for gate driver bias supply generation.
Input is 12V, & expecting output is 23V.
WE are using Wurth P/N 750319831
At starting only, we are getting this fault & no output is generated.
Also, wrongly in our schematic, this transformer was reversely connected. However, now we have changed the resonant frequency ( 408kHZ) we have tuned the resonant cap as 33nF.
Please help. Please revert back if any other data is required.
