Award-winning advanced bus converter upgraded to include burst-mode capability for peak power demand

Ericsson Power Modules’ award-winning BMR458 third-generation 3E* quarter-brick advanced bus converter has been upgraded to integrate burst-mode operation, which enables the module to handle 1079W of peak power for a brief period of time, up to a maximum of one second. Increasingly high-performance microprocessors and ASICs will require brief bursts of high current demand that is typically well in excess of normal system operation. Importantly, this burst-mode or peak-power capability eliminates the need for a second converter module to be placed in parallel. The device delivers industry-leading performance to system architects developing equipment for ICT applications, including datacom and server and storage systems. The module is ideal for high-power applications that are powered by multi-cell batteries or rectifiers commonly used in the ICT industry and employ IBC or DBV architectures. “This upgrade of the BMR458 meet the needs of leading customers to handle peak current, commonly demanded by the latest system processors, ASICs and other system-on-chip devices,” said Martin Hägerdal, head of Ericsson Power Modules. “Once again, Ericsson has extended its technological leadership with this further augmentation of capabilities to deliver the most advanced and highest power capable advanced bus converter available on the market today.”
