A digital, non-isolated voltage regulator estimated at 40A, the BMR451, was announced by Ericsson power modules. After the recent publication BMR450 rated 20A, the new device has a high density of the current 7.90A/cm3 (129A/in3)Thanks to its high power density and flexibility offered by the different functions integrated into the product, and offering the possibility to monitor the vital signs through the open standard PMBus interface, BMR451 adapted to a wide range of applications in information and communication technology - but is not limited to these two questions.
The BMR451 be adapted to new uses or applications to be upgraded to reduce energy consumption, and / or migration of passive energy for the active monitoring of energy use and management. Since the mid-bus architecture is not limited to ICT applications, because of its high power density and low profile (less than 8.5mm), the BMR451 is regarded as an ideal product for all applications space was Card and a good thermal performance are critical interest, such as in industrial process control, seal the box, test equipment or transportation applications. The small voltage regulators are easier to find close to FPGA, DSP and other processors, making the power failure and parasitic inductance issues.
Factors behind the need for this type of product are reducing consumption of energy produced by improving efficiency, but also the requirement of designers permanent access to strategic information of all the chain of service, the front-end of the rectifier loading point.
In comparison with existing products, Ericsson BMR451 offers an unparalleled level of functions (reading data back) via the open standard interface, PMBus. For system designers and architects, through PMBus access to strategic information, such as tax, the state of the load, temperature, the voltage differences, and many other parameters can Follow-level functions, without adding external components or circuitry.
In addition to cost savings and simplicity, resulting in fewer external components and embedded control, system architects now have the chance to follow through the power of each voltage regulator, perform low-level functions.
The PMBus read mode compatible BMR451 as 30.85mm x 20mm x 8.2mm, offers a 4.5V to 14V input voltage range, a 0.6 V to 3.6 V output voltage range and a 2.6 million hours MTBF figure. Through hole and surface mount versions are available.
Another important advantage of a digital controller is the ability for users to purchase pre-made modules that fit their applications ", such requirement ramp-up time, output voltage, alarms, etc. BMR451 also has a full range of standard features such as remote on / off, over temperature protection, output / voltage greater protection, input under-voltage protection and control Remote monitoring can be used to control redundancy.
The BMR451 has a "unique" serial number that refers to its chipset. This provides an unprecedented degree of traceability and the simplification of the administration party identification when performing diagnostics on board during the entire lifetime of the final equipment, says the company.
"It is with great pride, and with great appreciation for our development team worked from basic research through production of commercial products, as we launch 40A, digital BMR451," said Patrick Le Fèvre, marketing and communications Power Modules. "With this product, in combination with the recently released BMR450 rated 20A, and our success PMBus compliant 400W quarter-brick isolated BMR453 we are now allowing customers to a new era of applications that are optimized for energy efficiency, which unprecedented degree of flexibility to monitor and control through the open standard PMBus, low-energy component".
