Ericsson has extended its 3E digital power module family with two new digital-communication-bus-enabled 540 to 648W quarter-brick power interface modules (PIMs). Designed to meet the 300W industry-standard footprint and offering both I2C- and PMBus-based serial bus communications, the PIM4328PD and PIM4328PDA modules can help simplify board power monitoring and operational functionality without additional external components, thereby shortening time-to-market and reducing development costs.
Based on the company’s PIM4328P analogue platform, the addition of bus communication to the modules can help increase the flexibility offered by digital monitoring, including voltage/current input parameters. This makes it possible to evaluate power consumption at board level, which is vital for accurate efficiency monitoring and can aid compliance with energy efficiency legislation.
The information and communications technology industry is rapidly adopting PIM technology, which is also suitable for industrial, telecommunications or data communications applications employing distributed power architectures.
