Power design toolbox delivers board energy savings

Power design toolbox delivers board energy savings

Ericsson has introduced the world's first 'toolbox' that enables systems architects to optimize power profiles and energy configuration prior to implementation in end equipment.

The 3E Design Toolbox includes a set of five modules that can be operated as stand-alone devices or interconnected to mirror complex applications requiring multiple power rails with specific configuration profiles such as sequencing, tracking, and load sharing and distribution. The toolbox also includes the Ericsson 3E software, which, via the USB/PMBus interface, can monitor, configure and control any Ericsson 3E or PMBus-compliant unit connected to the boards.

The Ericsson 3E Design Toolbox includes the ROA1285151 (PIM Module) which hosts a combined socket that is compatible with the industry-standard 400W PIM4300 series of power interface modules and the recently launched 800W PIM4800 series, including PMBus interface, hold-up capacitors and all the required circuitry to mirror the input stage that is commonly used in ICT (Information and Communications Technology) applications.

The ROA1283835 (ABC Module) has room for two Advanced Bus Converters (ABCs) from the FRIDA I series - the quarter-brick BMR453 and eighth-brick BMR454 - and the FRIDA II series' quarter-brick BMR456 and shortly available eighth-brick BMR457.

The ROA1283836 (3E POL PI Module) is equipped with six connectors making it able to host hole-through 3E Point-Of-Load (POL) converters. Two sockets are dedicated to the 40 A BMR464; four can host the 20 A BMR463; and additionally, two out the four can be used for the 12 A BMR462. For simple systems, each 3E POL can be tested independently from the others or, for more advanced power configuration, combined in different ways such as paralleling.
