EVL8030-QJ-00B 41-57V, 6A PoE PD Evaluation Board QFN-32

The MPS EVL8030-QJ-00B is an evaluation board built around the MP8030 for bench characterisation of the device in its intended topology. It operates from a 41 V to 57 V input and is rated for 6 A. The board carries the device in its QFN-32 package.

The EVL8030-QJ-00B is an evaluation board designed to demonstrate the capabilities of the MP8030, a fully integrated, IEEE 802.3af/at/bt compatible, power over Ethernet (PoE) powered device (PD) with a PD interface and high-efficiency, primary-side regulated (PSR) flyback controller.

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.
