Other Parts Discussed in Thread: TPS22918
Hello,
I have following schematic:
The transistor at ON pin is not populated and CT=100p.
And I get following measurement:
I'm surprised that level at ON pin go to ~2,6V when IN is 1,8V.
Could this be related to the charge pump inside the IC? Is it "normal" to have ~2,6V at the ON pin? Why did we have a "step" at the on pin voltage the first 2ms?
And I have the same circuit with 3,3V input and I have also ~2,6V at ON pin!
Regards,
