Ericsson has announced an extension of its 3E digital power module family with two new digital-communication-bus-enabled 540-648W low-profile quarter-brick Power Interface Modules (PIMs). Compliant with the 300W de facto industry-standard footprint and offering both I2C- and PMBus-based serial bus communications, the PIM4328PD and PIM4328PDA modules simplify board power monitoring and operational functionality without the need for additional external components, thereby shortening time-to-market and reducing development costs.
Based on the company’s high-efficiency PIM4328P analog platform, the addition of bus communication to the modules increases the level of flexibility offered by digital monitoring, including voltage/current input parameters, making it possible for systems architects to evaluate the power consumption at board level – an important parameter to accurately monitor efficiency and also aid system compliance with energy efficiency legislation, where necessary.
Originally designed for Advanced Telecom Computing Architecture (ATCA) applications – because of the huge benefits delivered by a standalone module in terms of board space and time-to-market – the Information and Communications Technology industry is rapidly adopting PIM technology, which is becoming an increasingly important component for system designers in the migration to new platforms.
