Q. How to monitor the LX and BYP pins on the MAX77818EVKIT?
A. The PBC layout of the MAX77818EVKIT has a couple of vias that connect directly to the LX and BYP pin as indicated in the schematic of the MAX77818EVKIT.
You scrape part of the ground place next to the vias labeld LX and VBYP on the Evaluation kit, and install a wire loop to place a x10 oscilloscope probe with the shortest connections to ground to prevent long ground connections as indicated in the following pictures.
NOTE:It is best to use a 10X probe since it provides a lower capacitive load on the tested circuit. Or implement a FET probe for your tests.
