Exar XRP7714EVB-DEMO-2P Demo Boards
Exar XRP7714EVB-DEMO-2P Demo Boards are complete, working, four-channel power systems featuring the XRP7714 programmable controller. Exar XRP7714EVB-DEMO-2P 2" x 2.5" Demo Boards are capable of producing over 35W and provide 3.3V, 2.5V, 1.8V, and 1V at a maximum of 4A per channel. The 2.5V, 1.8V, and 1V supplies can be adjusted in 50mV increments, and the 3.3V supply is adjustable in 100mV increments. The order and ramp rates for each supply can be programmed to accommodate any sequencing requirement. All power supply operations can be controlled over an I²C interface. Faults, output voltages, and currents can also be monitored. Four GPIO signals are available and can be programmed to provide status of power good signals enables and faults. Unused GPIO pins can be programmed as I/O expansion for a microcontroller. The board is supported by PowerArchitect™ and plugs directly onto the Exar Communications Module (XRP77xxEVBXCM).
