EV8770-Q-00A 4.5-17V, 8A Step-Down Converter Evaluation Board QFN-16
The MPS EV8770-Q-00A is an evaluation board built around the MP8770 for bench characterisation of the device in its intended topology. It operates from a 4.5 V to 17 V input, is rated for 8 A and switches at 700 kHz. The board carries the device in its QFN-16 package.
The EV8770-Q-00A Evaluation Board is designed to demonstrate the capabilities of MPS' MP8770, a fully-integrated 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.
