EV8008-V-00A TM The Future of Analog IC Technology Fully-Integrated IEEE 802.3af/at-Compliant PoE PD Interface with Peak Current Mode Flyback Controller Evaluation Board TM DESCRIPTION FEATURES EV8008-V-00A Evaluation Board is designed to demonstrate the capability of MP8008`s function. The MP8008 is an integrated IEEE 802.3af/at PoE compliant Powered Device (PD) power supply converter. It includes PD interface and peak current mode flyback controller. The PD interface has all the functions of IEEE 802.3af/at, and sets 120mA inrush current limit, 840mA operation current limit as well as 100V Hot-swap MOSFET. The flyback PWM controller can drive an external MOSFET capable of handling more than 10A current. PSM function improves the efficiency in light load condition. The MP8008 flyback also features protection including over load, short output and over voltage protection. The MP8008 can support a front-end solution for PoE-PD application, it is available in QFN28 (4mmX5mm) package.

All Rights Reserved. 8 TM EV8008-V-00A—IEEE 802.3AF/AT-COMPLIANT POE PD INTERFACE WITH FLYBACK CONTROLLER EVB 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 EV8008-V-00A. 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 (+): VDD b. Negative (–): VSS 4. Connect Load to: a. Positive (+): VOUT b. Negative (–): VOGND 5. Turn Power Supply on after making connections. 6. The MP8008 is enabled on the evaluation board once VIN is applied. 7. To use adapter supply function, connect the 12V adapter`s positive terminal to VDD and negative terminal to APD-GND, then turn on the adapter, the board will prior use adapter to supply itself. When use this adapter function and load current is heavy, some components` temperature should be high, it is limited by board size.
