EV7748S-F-00A 9.5-36V Channels SE and BTL Class D Audio Amplifier Evaluation Board

The MPS EV7748S-F-00A is an evaluation board built around the MP7748S for bench characterisation of the device in its intended topology. It operates from a 9.5 V to 36 V input.

The EV7748S-F-00A is the 2.1 channels configuration evaluation board for the MP7748S, a 30W Single-ended or 60W Mono Class D Audio Amplifier.

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.
