Increasingly, computer-based systems employ digital control of power supplies to improve power-management flexibility, maintainability, and reliability.
Standardized PMBus commands encourage semiconductor and powersupply manufacturers to develop the appropriate technology to control a power supply's operating parameters, monitor its operation, and perform corrective measures in response to faults or operational warnings.
Starting with 45 executable commands, the PMBus specification will expand as new technologies and circuit configurations evolve.
Semiconductor and power-supply manufacturers use Windows-based
GUIs to support PMBus designs.
Evaluation boards help designers understand PMBus operations.
The greater use of online design and simulation tools helps to optimize power-supply operation and verify its performance.
