Monolithic Power Systems MP8030 | Demoboard EVL8030-QJ-01A

Description

The EVL8030-QJ-01A is an evaluation board designed to demonstrate the capabilities of the MP8030, a fully integrated, IEEE 802.3af/at/btcompatible,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-powered applications. The second gate driver (GATE2) supports an external, low RDS(ON) N-channel MOSFET to reduce high-power loss while the controller is powered from via 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.
