Unauthorized Photocopy and Duplication Prohibited. © 2015 MPS. All Rights Reserved. TM QUICK START GUIDE The output voltage of this board is set to 12V. The board layout accommodates most commonly used components. There are two methods to start MP8007. Method 1: 1. Connect Load to: a. Positive (+): VOUT b. Negative (–): VOGND 2. Plug the cable coming from the PSE into the Ethernet Jack J1. The board will automatically startup. Method 2: 1. Preset Power Supply to 40V ≤ VIN ≤ 57V. (It can work in 37V ≤ VIN ≤ 57V after power up.) 2. Turn Power Supply off. 3. Connect Power Supply terminals to: a. Positive (+): VIN b. Negative (–): VSS 4. Connect Load to: a. Positive (+): VOUT b. Negative (–): VOGND 5. Turn Power Supply on after making connections. 6. The MP8007 is enabled on the evaluation board once VIN is applied. 7. MP8007 can supply V CC through internal high voltage LDO, D6 and R10 can be removed to save BOM cost, while it may lead to about 0.2% efficiency decreasing. 8. To use adapter supply function, connect the adapter\`s positive terminal to VIN and negative terminal to ADPGND, then turn on the adapter, the board will prior use adapter to supply itself.
