I not getting the following voltages
1v3 V
2v9v from VSYS
1v05v from 1v3V
1v05v from 1V3V
I supply power from my bench supply and connect it to the USB shield and the bottom of the inductor shown in Image 1.
I turn on the switch by shorting the pins 1 and 2 of the power button ribbon connector (Image 2), and the current drawn is 0.11A (Limited to 1A), as shown in Image 3
I then measured the voltages at the points shown in Image 4 (MAX77620). The red arrows show where I got no voltages. From the diagram, they are
1.3V, 2.9V, 1.3V and 1.05V
Any ideas ?
