Description

MPL

Optimized Performance with MPS Inductor

The EVL8030-QJ-01A 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 a high-efficiency forward controller.

The PD interface has all the functions of IEEE 802.3af/at/bt. It integrates a 100V hot-swap MOSFET and a gate driver (GATE1) to improve efficiency for high-power applications.

The second gate driver (GATE2) supports an external, low R_DS(ON) N-channel MOSFET to reduce high power loss while the controller is powered by an adapter.

The controller is designed for both primary-side regulation (PSR) in flyback applications and secondary-side regulation (SSR) in active-clamped forward applications.

It is recommended to read the MP8030 datasheet prior to making any changes to the EVL8030-QJ-01A.
