MEZS7-SolarCharger 4.5-16V Wide Input Range 4.5A I2C Controlled SW Charger Evaluation Board
The MPS MEZS7-SolarCharger is an evaluation board built around the MP2731 for bench characterisation of the device in its intended topology. It operates from a 4.5 V to 16 V input and is rated for 4.5 A.
The MEZS7-SolarCharger is a complete solution module that uses the MP2731 NVDC buck charger with an MCU for maximum power point tracking (MPPT) designs with a photovoltaic (PV) panel.

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.
