EVBL4571-QB-00A 5-60V, 1A Synchronous Step-Down Converter Evaluation Board QFN-12
The MPS EVBL4571-QB-00A is an evaluation board built around the MP4571 for bench characterisation of the device in its intended topology. It operates from a 5 V to 60 V input and is rated for 1 A. The board carries the device in its QFN-12 package.
The EVBL4571-QB-00A is an evaluation board designed to demonstrate the capabilities of the MP4571, a high-efficiency, synchronous step- down converter with integrated internal power MOSFETs (HS-FET and LS-FET, respectively).

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.
