EVM3840-QV-00A 2.8-5.5V, 4A Synchronous Step-Down Converter Evaluation Board QFN-20
The MPS EVM3840-QV-00A is an evaluation board built around the MPM3840 for bench characterisation of the device in its intended topology. It operates from a 2.8 V to 5.5 V input, is rated for 4 A and switches at 1.2 MHz. The board carries the device in its QFN-20 package.
The MPM3840 is a monolithic step-down converter with built-in internal power MOSFETs and inductor.

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.
