数字控制器，用于隔离型电源使用PMBus接口 Digital Controller for Isolated Power Supply with PMBus Interface
The is an evaluation kit for ADP1051 digital controller for isolated power supply with PMBus interface. The ADP1051 is an advanced digital controller with a PMBus interface targeting high density, high efficiency DC to DC power conversion. The ADP1051-240-EVALZ evaluation board, together with a ADP1051DC1-EVALZ daughter card, allows the user to evaluate the ADP1051 in a power supply unit PSU environment. The boards are fully compatible with the ADP1051 GUI software. With the ADP-I2C-USB-Z USB to I2C connector and the GUI software, the ADP1051 on the evaluation board can be interfaced with a PC via a USB port. The evaluation board allows the ADP1051 to be exercised without the need of external components. Two parallel connectors on the evaluation board provide synchronization, share bus and PMBus interfaces. They allow the direct paralleling evaluation when multiple evaluation boards are connected in parallel to a common bus.
