EVQ4456-QT-00A 3.8-36V, 1A Step-Down Converter Evaluation Board QFN3
The MPS EVQ4456-QT-00A is an evaluation board built around the MPQ4456 for bench characterisation of the device in its intended topology. It operates from a 3.8 V to 36 V input, is rated for 1 A and switches at 4 MHz. The board carries the device in its QFN3 package.
The EVQ4456-QT-00A is an evaluation board for the MPQ4456, a high frequency step-down regulator with an integrated power MOSFET.

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.
