400W power interface moduleEricsson Power Modules announced the PIM4328P, a new 390 W to 540 W power interface module (PIM) compliant with the 300-W de facto industry-standard footprint. The quarter-brick module is said to simplify design in blade servers based on Advanced TCA (PICMG 3.0) systems. The company asserts its low-EMI design rules and best practices ensure that minimal external filtering is needed to meet the CISPR Class B EMC standards required for Information and Communications Technology (ICT) applications. Ripple and noise are minimized. The PIM4328P operates over an input range of 36 V to 75 V, and the main unit is able to sustain a permanent output current of 10 A without forced airflow up to +70?C and up to +90?C with 2.0 m/s (400 lfm). Output power is 390 W at minimum 39V input and up to 540W when the input is minimum 54 V. This allows headroom when there is a need to upgrade boards with new processors or additional memory in systems operating in battery or non-battery back-up applications. With 99 percent typical efficiency at 300-W output, the PIM4328P maintains the standards of dynamic and load step performance required in ATCA equipment while limiting power losses across the filtering unit to a very low level.
