EVBL9840-L-00A 3.3-36V, 3.5A Step-Down Switch-Mode Convertor Evaluation Board

The MPS EVBL9840-L-00A is an evaluation board built around the MP9840 for bench characterisation of the device in its intended topology. It operates from a 3.3 V to 36 V input and is rated for 3.5 A.

The EVBL9840-L-00A is an evaluation board designed to demonstrate the capabilities of the MP9840 and the MPQ9840.

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.
