The EV5990-5991-V-5PHASE-00A evaluation board is designed to demonstrate the capabilities of the MP5990 while working in parallel with multiple MP5991 devices. The MP5990 is a fully integrated, PMBus-compatible, compact hot-swap protection device. It contains a hot-swap controller and a high-side power MOSFET (HS-FET), which allow it to operate as a standalone device. The MP5990 can also operate as a hot-swap controller in parallel with the multi-phase MP5991. The evaluation board contains one phase of the MP5990 and four phases of the MP5991.

The EV5990-5991-V-5PHASE-00A provides rich test pins and LED indications to simplify system evaluation. The paralleled MP5990’s and MP5991’s pins can be probed through the test pins, helping the user easily understand the MP5990’s operating principles.

The EV5990-5991-V-5PHASE-00A is compatible with discrete power source terminals and a power supply unit (PSU) interface, which meet different power supply verification requirements.

The MP5990 supports PMBus communication. Through the PMBus interface, the MP5990 can both monitor and report fault statuses, and set up configurations. The built-in non-volatile memory (NVM) supports storing custom configurations.

The MP5990 is available in an LGA-45 (5mmx7mm) package, and the MP5991 is available in an LGA-32 (5mmx5mm) package. The EV5990-5991-V-5PHASE-00A has 4 layers, which are each 2oz. The total size of the board is 11cmx15cm.
