EV4423H-Q-00A 4-36V, 3A Synchronous Step Down Converter Evaluation Board QFN-8
The MPS EV4423H-Q-00A is an evaluation board built around the MP4423H for bench characterisation of the device in its intended topology. It operates from a 4 V to 36 V input, is rated for 3 A and switches at 410 kHz. The board carries the device in its QFN-8 package.
The EV4423H-Q-00A is an evaluation board for the MP4423H/MPQ4423H, a high-frequency, synchronous, rectified, step-down, switch-mode converter with build-in power MOSFETs.

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.
