GUI reduces design time of intelligent power supplies used in high-reliability server, storage, and communications infrastructure apps

A digital power controller for ac/dc and isolated dc/dc power supplies in high-reliability server, storage, and communications infrastructure equipment, the ADP1043 digital PWM power control and management IC can configure system power-supply parameters in a matter of minutes using a GUI. The device helps system integrators optimize power supply energy efficiency, while reducing design cycle time and enabling intelligent power management systems.

The device uses an application-specific, on-chip digital control engine that works in concert with the GUI and an I2C interface.The company claims the design helps reduce component count over competing analog and digital power controllers.

The single-chip device integrates on-chip technology for isolated power conversion, housekeeping, and monitoring that enables the practical implementation of more energy efficient power supply designs. It includes a seven-output PWM; on-board memory for program and data storage; the choice of traditional analog or open-standard digital current-sharing schemes for parallel power supply operation; MOSFET OR-ing control for redundant power supply operation; and differential voltage sensing and trimming, which can be programmed via the I2C interface.
