The EV3908DK-00B is a synchronous boost converter evaluation board for the MP3908DK. It is configured to provide a regulated 19V output at up to5Aload current from a 7V-17V input. The output is adjustable by changing feedback resistors on the evaluation board.

The demo board uses the external 6.7mΩ resistor to sense the current and MP6901DS to drive a low Ron mosfet as rectifier to achieve high efficiency. MP6901DS is a Low-Drop Diode Emulator IC which works with an external switch to replace Schottky diode.
