Digital power controller speeds design of intelligent supplies

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 I2 C 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 I2 C interface.
