EVQ2179-LE-00A 2.5-5.5V, 3A Synchronous Step-Down Converter Evaluation Board QFN-8
The MPS EVQ2179-LE-00A is an evaluation board built around the MPQ2179 for bench characterisation of the device in its intended topology. It operates from a 2.5 V to 5.5 V input, is rated for 3 A and switches at 2.4 MHz. The board carries the device in its QFN-8 package.
The EVQ2179-LE-00A is is an evaluation board designed to demonstrate the capabilities of the MPQ2179, a monolithic, step-down switch- mode converter with built-in internal power MOSFETs.

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.
