EV7748DF-00B 9.5-36V Mono Bridge Tied Load Class D Audio Amplifier Evaluation Board TSSOP28
The MPS EV7748DF-00B is an evaluation board built around the MP7748 for bench characterisation of the device in its intended topology. It operates from a 9.5 V to 36 V input. The board carries the device in its TSSOP28 package.
The EV7748DF-00B is the BTL(Bridge Tied Load) configuration evaluation board for the MP7748, a 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.
