EVQ4436A-R-00A 3.3-45V, 6A Step-Down Converter Evaluation Board QFN-20
The MPS EVQ4436A-R-00A is an evaluation board built around the MPQ4436A-AEC1 for bench characterisation of the device in its intended topology. It operates from a 3.3 V to 45 V input and is rated for 6 A. The board carries the device in its QFN-20 package.
The EVQ4436A-R-00A evaluation board is designed to demonstrate the capabilities of MPS's MPQ4436A-AEC1 and MPQ4436A.

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.
