The XRP7740EVB-HIC Demo board is a complete, four channel, power system measuring 3.25” x 5” capable of delivering over 60 watts. It provides 1.5V, 1.0V 1.8V and 1.0V at a maximum of 8A, 30A, 5A and 12A on channels 1 through 4 respectively. All power supply operations can be controlled over an I2C interface. The supplies can be adjusted in 50mV increments for voltages up to 2.5V and in 100mV increments for voltages from 2.6V to 5.1V. The order and ramp rates for each supply can be programmed to accommodate any sequencing requirement. Faults, output voltages and currents can also be monitored. Four GPIOs are available and can be programmed to provide status of power good signals, faults, and warnings or as enable inputs. Unused GPIO pins can be programmed as I/O expansion for a microcontroller. The board is supported by PowerArchitectTM 4.21 and plugs directly onto the Exar Configuration Module (XRP77XXEVB-XCM).
