This evaluation board, together with a daughter card, allows you to evaluate the ADP1055 as a power supply application.With the USB to I2C connector, and the graphical user interface (GUI), the ADP1055 on the evaluation board can be interfaced with a PC via a USB port. The evaluation board is set up to act as an isolated PSU with a rated load of 12 V, 20 A from a 38 V dc to 60 V dc source. Connectors on the evaluation board provide synchronization,as well as share bus and PMBus™ interfaces, allowing directparallel evaluation when multiple evaluation boards are connected in parallel to a common bus. Multiple test points allow easy access to all critical points/pins.
