EV4570-F-01A 4.5-55V, 3A Frequency Programmable Step-Down Converter Evaluation Board
The MPS EV4570-F-01A is an evaluation board built around the MP4570 for bench characterisation of the device in its intended topology. It operates from a 4.5 V to 55 V input and is rated for 3 A.
The EV4570-F-01A is an evaluation board for the MP4570/MPQ4570, a frequency programmable step-down switching converter with integrated internal high-side and low side 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.
