Ericsson power modules new footprint-compatible DC/DC deliver increased flexibility in power system design

New 6A and 18A output variants join BMR461 family of advanced DC/DC point-of-load (POL) regulator modules. 100 percent-compatible footprint means wide choice of output capability while retaining board design simplicity. Duo of modules offer high performance without compromising on dynamic response. Auto-compensated digital POL regulators based on ‘state-space’ or ‘model-predictive’ control, reducing cost and time-to-market while increasing flexibility.

Ericsson has introduced two new 3E* DC-DC regulators to its family of BMR461 12 x 12 x 8mm digital point-of-load (POL) modules. The two new variants in the BMR461 family offer current outputs of 6A (BMR4612001) and 18A (BMR4614001) and join the existing 12A version (BMR4613001) launched toward the end of last year. Like the 12A BMR461 regulator, these two new modules also deliver Dynamic Loop Compensation (DLC), advanced energy-optimization algorithms to reduce energy consumption, low-bias current technology, and a land-grid-array (LGA) footprint that guarantees excellent thermal, mechanical and electrical performance.

"The launch of these two new 6A and 18A advanced POL modules is yet another demonstration of Ericsson’s industry-leading design capabilities that provide advanced performance while simplifying the design process, thereby easing processor upgradability and shortening the time-to-market," said Patrick Le Fèvre, Marketing and Communication Director, Ericsson Power Modules. "Along with other advanced performance options, these new modules also offer Dynamic Loop Compensation circuitry like the 12A variant, negating the requirement for external components such as RC networks to adjust control loop compensation parameters."

A very important feature of the two new modules is that they are 100 percent footprint compatible with the existing 12A BMR4613001 product. This means that customers will now have availability of these advanced POL regulators that offer three different output currents – 6A, 12A and 18A – while only having to handle a single module footprint in new systems. This significantly simplifies board design and makes it easier for power architects to move to higher or lower current-handling power modules without needing to redesign the system board when upgrading to new microprocessors or other advanced logic devices such as FPGAs or ASICs.
