EVQ4423C-L-00A 6A Step-Down Converter Evaluation Board QFN-16
The MPS EVQ4423C-L-00A is an evaluation board built around the MPQ4423C for bench characterisation of the device in its intended topology. It is rated for 6 A and switches at 2.2 MHz. The board carries the device in its QFN-16 package.
The EVQ4423C-L-00A evaluation board is designed for the MPQ4423C, a high-frequency, synchronous, rectified, step-down switch-mode converter with built-in 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.
