EV9151-D-00A 5-20V 20V, 4A 800kHz Synchronous Step-down Converter EV Board Evaluation Board QFN2
The MPS EV9151-D-00A is an evaluation board built around the MP9151 for bench characterisation of the device in its intended topology. It operates from a 5 V to 20 V input, is rated for 4 A and switches at 800 kHz. The board carries the device in its QFN2 package.
The EV9151-D-00A is for demonstrating MPS's MP9151, a high-frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs.

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.
