EVQ4433-L-00A 5-36V, 3A Low Quiescent Current Synchronous Step-Down Convertor Evaluation Board QFN-16
The MPS EVQ4433-L-00A is an evaluation board built around the MPQ4433 for bench characterisation of the device in its intended topology. It operates from a 5 V to 36 V input and is rated for 3 A. The board carries the device in its QFN-16 package.
The EVQ4433-L-00A Evaluation Board is designed to demonstrate the capabilities of MPS' MP/MPQ4433.

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.
