XRP7714EVB-DEMO-2P-KIT: 4 Chan, 4A, 4.5 ~ 25V in

Summary

The XRP7714EVB-DEMO-1, XRP7714EVB-DEMO-2, and the XRP7714EVB-DEMO-2P demo boards are complete, working, four channel, power systems measuring either 2”x2”, or 2”x2.5” capable of delivering over 35 watts. They provide 3.3V, 2.5V, 1.8V, and 1V at a maximum of 4 amps 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 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 (XRP77XXEVB-XCM).
