The default configuration provides 1.8V and 2.5V at maximum loads of 6Amps per output. The supplies can be dynamically adjusted in 5mV increments. The order and ramp rates for each supply can be programmed to accommodate any sequencing requirement. All power supply 2 operations can be controlled over an I C interface. Faults, output voltages and currents can also be monitored. Two GPIO and three PSIO signals are available and can be programmed to provide a variety of functions. Unused GPIO/PSIO pins can be programmed as I/O expansion for a microcontroller. The TM board is supported by PowerArchitect 5.1 or later, and plugs directly onto the interposer board acting as an interface to Arduino controller.
