Monolithic Power Systems (MPS) EV5990-5991-V-5PHASE-00A Evaluation Board
Monolithic Power Systems (MPS) EV5990-5991-V-5PHASE-00A Evaluation Board demonstrates the capabilities of the MP5990 while working in parallel with multiple MP5991 devices. The MP5990 is a compact, fully integrated, PMBus-compatible, hot-swap protection device. It contains a high-side power MOSFET (HS-FET) and a hot-swap controller, which allows it to operate as a standalone device. The MP5990 can operate as a hot-swap controller in parallel with the multi-phase MP5991. The evaluation board contains four phases of the MP5991 and one phase of the MP5990.
The EV5990-5991-V-5PHASE-00A provides rich test pins and LED indications to simplify system evaluation. The user can easily understand the MP5990’s operating principles using the paralleled MP5990 and MP5991 pins that can be probed through the test pins. The EV5990-5991-V-5PHASE-00A is compatible with discrete power source terminals and a power supply unit (PSU) interface, which meets different power supply verification requirements.
The MP5990 supports PMBus communication. Through the PMBus interface, it can monitor and report fault statuses and set up configurations. The built-in non-volatile memory (NVM) supports strong storage of custom configurations. The MP5991 is available in an LGA-32 (5mm x 5mm) package, and the MP5990 is available in an LGA-45 (5mm x 7mm) package. The Monolithic Power Systems (MPS) EV5990-5991-V-5PHASE-00A has four layers, each 2oz. The total size of the board is 11cm x 15cm.
