Evaluation Board

Design Notes

• The board ships in a default configuration; check the jumper and resistor options against the user guide before applying power.
• Respect the input terminal rating — most faults on evaluation boards come from an supply above the marked limit.
• Test points on the switching node and output are for a short-ground probe, not for a long oscilloscope lead.
• Where a GUI is supported, connect the dongle before power-up so the device enumerates on the I²C bus.
