EVL8030-QJ-01A

EVL8030-QJ-01A IEEE 802.3af/at/bt-Compatible, PoE PD with PD Interface and SSR Forward Controller Evaluation Board 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 activeclamped forward applications. It is recommended to read the MP8030 datasheet prior to making any changes to the EVL8030-QJ-01A. PERFORMANCE SUMMARY Specifications are at TA = 25°C, unless otherwise noted. Parameters Input voltage (VIN) range Output voltage (VOUT) Maximum output current (IOUT) Full load efficiency Switching frequency (fSW) Conditions VIN = 41V to 57V, IOUT = 0A to 14A VIN = 41V to 57V VIN = 54V, VOUT = 5V, IOUT = 14A Value 41V to 57V 5V 14A 92.2% 250kHz EVALUATION BOARD LxWxH (16.3cmx5.2cmx2cm) 4-Layers, 2oz/1oz/1oz/2oz Board Number EVL8030-QJ-01A MPS IC Number MP8030GQJ EVL8030-QJ-01A Rev. 1.0 MonolithicPower.com 10/25/2021 MPS Proprietary Information.

There are two methods to startup the EVL8030-QJ-01A, which are listed below. Figure 1 shows the connections for both methods. Method 1: 1. Connect the load terminals to: a. Positive (+): VOUT b. Negative (-): VOGND 2. After making the connections. plug the Ethernet cable of the power-sourcing equipment (PSE) into the Ethernet jack (J1). The board should start up automatically. Method 2: 1. Preset the power supply between 41V and 57V, then turn off the power supply. 2. Connect the power supply terminals to: a. Positive (+): VDD b. Negative (-): VSS 3. Connect the load terminals to: a. Positive (+): VOUT b. Negative (-): VOGND 4. After making the connections, turn on the power supply. The board should start up automatically. 5. The MP8030 is enabled once the VDD pin voltage (VDD) is applied. To use the adapter supply function, follow steps 6 and 7: 6. Connect the adapter terminals to: a. Positive (+): ADAPOT b. Negative (-): ADAPOT-GND 7. After making the connections, turn on the adapter. The board should be supplied via the adapter automatically.
