EV4473-L-00A 4.5-36V, 3.5A Step-Down Converter Evaluation Board QFN20
The MPS EV4473-L-00A is an evaluation board built around the MPQ4470 for bench characterisation of the device in its intended topology. It operates from a 4.5 V to 36 V input and is rated for 3.5 A. The board carries the device in its QFN20 package.
The EV4473-L-00A is an evaluation board for the MPQ4470, a high-efficiency step-down regulator with integrated 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.
