EVQ8861-LE-00A 2.9-18V, 12A Synchronous Step-Down Converter Evaluation Board QFN-14
The MPS EVQ8861-LE-00A is an evaluation board built around the MPQ8861 for bench characterisation of the device in its intended topology. It operates from a 2.9 V to 18 V input and is rated for 12 A. The board carries the device in its QFN-14 package.
The EVQ8861-LE-00A is an evaluation board designed to demonstrate the capabilities of the MPQ8861, a high-frequency, synchronous, rectified, step-down, switch-mode converter with an I2C interface.

Evaluation Board
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.
