EV4581-N-00A 10-100V, 0.8A Synchronous Buck Converter Evaluation Board SOIC8E
The MPS EV4581-N-00A is an evaluation board built around the MP4581 for bench characterisation of the device in its intended topology. It operates from a 10 V to 100 V input, is rated for 0.8 A and switches at 1 MHz. The board carries the device in its SOIC8E package.
The EV4581 Evaluation Board is designed to demonstrate the capabilities of MPS' MP4581.

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.
