Dear,
we fine tune RDC to EN pin ,but find the Iin (peak to peak) was too High, is could be normal behavior?
Vin=3V, R=21.98K+C=1uF as below chart: ; V p-p=1.19902A
Vin=3v R=50.95K+C=2.2uF ; V p-p=1.07706A
If any…

Hello Lawrence,
1. VGH phenomenon:
I expect VDD is the input voltage VIN in the schematic, correct? At the moment when VGH shows the fluctuation, VDD seems to be very close to the UVLO voltage. I think the IC going into and out of UVLO during this…
