EVM3805-QB-01A 2.5-6V, 0.6A Synchronous Step-Down Switcher Evaluation Board QFN3
The MPS EVM3805-QB-01A is an evaluation board built around the MPM3805 for bench characterisation of the device in its intended topology. It operates from a 2.5 V to 6 V input and is rated for 0.6 A. The board carries the device in its QFN3 package.
The EVM3805-QB-01A is used for demonstrating the performance of MPS's MPM3805 a low voltage high switching frequency step-down switcher with built-in power MOSFETs and power 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.
