EVL2491C-QB-00A 4-32V, 6A Step-Down Converter Evaluation Board QFN-13

The MPS EVL2491C-QB-00A is an evaluation board built around the MP2491C for bench characterisation of the device in its intended topology. It operates from a 4 V to 32 V input, is rated for 6 A and switches at 490 kHz. The board carries the device in its QFN-13 package.

The EVL2491C-QB-00A is an evaluation board designed to demonstrate the capabilities of the MP2491C, a high-voltage, step-down converter with a configurable current limit and output voltage (VOUT) scaling.

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.
