Power Manager Governs Six DC/DC Converters

The PS-2606 digital power controller is capable of managing up to six, non-isolated dc/dc converters and one intermediate bus in telecom, networking and data storage applications. Described as a highly integrated device, it allows users to digitally program output voltages, interlocked sequencing for startup and shutdown, and over-voltage and under-voltage warning and fault thresholds on each power rail. Configuration is accomplished via PowerCenter Designer software, which validates designs employing any type of dc/dc converter, including standard POLA and DOSA modules. All secondary-side data managed by the controller is accessible to system-level processors through an I2C interface. Other features include an isolated PI-Link interface that accepts voltage, fuse status, and fault data from the company's primary side power-management ICs. For higher rail-count systems, multiple controllers can be cascaded. Price is $6 each/10,000. POTENTIA SEMICONDUCTOR, Ontario, Canada. (613) 592-0027
