EVBL4473-L-00A 4.5-36V, 3.5A Step-Down Converter Evaluation Board QFN-20
The MPS EVBL4473-L-00A is an evaluation board built around the MPQ4473 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 QFN-20 package.
The EVBL4473-L-00A evaluation board is designed to demonstrate the capabilities of the MP/MPQ4473, a high-efficiency, step-down regulator that features an MPS power inductor and integrated power MOSFETs.

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.
