EV2155-Q-00A 2-5.5V DC/DC Buck-Boost Converter Evaluation Board QFN-10
The MPS EV2155-Q-00A is an evaluation board built around the MP2155 for bench characterisation of the device in its intended topology. It operates from a 2 V to 5.5 V input and switches at 1 MHz. The board carries the device in its QFN-10 package.
The EV2155-Q-00A is an evaluation board designed to demonstrate the capabilities of the MP2155, a highly efficient, low quiescent current (IQ), buck-boost converter.

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.
