EVQ4573-QB-00A 5-60V, 2.5A Synchronous Buck Converter Evaluation Board QFN-12
The MPS EVQ4573-QB-00A is an evaluation board built around the MPQ4573-AEC1 for bench characterisation of the device in its intended topology. It operates from a 5 V to 60 V input and is rated for 2.5 A. The board carries the device in its QFN-12 package.
The EVQ4573-QB-00A is an evaluation board designed to demonstrate the capabilities of the MPQ4573-AEC1, a fully integrated, fixed- frequency, synchronous step-down converter.

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.
