130-Watt Boost Modules Convert from 12 Volts to up to 54 Volts

Building on its existing line of dc-dc boost converters and offering more versatility to board designers, GE's Industrial Solutions has introduced two new additions to its BoostLynx product family—ABXS003A3X341-SRZ (a high-voltage version) and ABXS005A4X341-SRZ (its low-voltage counterpart).

The additions to GE's line of non-isolated, high-efficiency dc-dc voltage converters increase the load capacity of the product family to up to 130W, equipping board designers with a range of solutions to meet the demands of today's power-hungry applications.

The new 130-W BoostLynx modules can convert a standard 12-Volt bus voltage (which supports an input voltage range of 8- to 16-V) to higher voltages of 16- to 34-V with GE's low-voltage ABXS005 version and to between 32- and 54-V with the high-voltage ABXS003 version.

The easy-to-use BoostLynx converters—also known as point-of-load (PoL) modules—can be used to power any component with an operating voltage between 16- and 54-V. For example, the PoL modules could be used in applications such as small-cell remote radio heads, radio frequency power amplifiers, LED backlighting, solenoids and actuators in machinery and automation, fans, surveillance cameras and equipment, sensors and robotics.

"The technology we use on a day-to-day basis continues to evolve around us. With these new and improved solutions comes a hunger for more power," said Vesa Jokitulppo, senior product manager, GE's Industrial Solutions. "Improving power capabilities and efficiencies of these solutions starts at the board level.

"By designing embedded components to provide more power and perform better in similar (or, in some cases, smaller) footprints, we are able to help improve the functionality of the end solutions that we have all become so dependent on.

"It's what we set out to accomplish with these additions to our BoostLynx product family—which is now able to power any electronic components with an operating voltage of between 16- and 54-Volts," stated Jokitulppo.

GE's fully integrated BoostLynx dc-dc converters use minimal board space, enabling them to provide a high power density of approximately 125 W/inch2. The modules also save space and costs when paired with one of GE's CLP 150-450-W rectifiers (with an input voltage of between 90- and 264-Vac and an output 12Vdc), as electronic components with both 0.6- to 5.5-V and 16- to 54-V operating voltages can now be powered from a common 12-Vdc bus—with a combination of buck and boost PoL converters.

In addition, the modules' flat top inductors make them suitable for conduction cooling—a highly desirable feature in applications with little or no airflow or in demanding thermal environments, and their IPC9592 Class II qualification helps ensure high reliability.

"With our new BoostLynx offerings, we are able to provide increased power capabilities without having to overhaul power architectures by stepping up standard 12-Volt power to the voltage needed in these power-hungry devices," Jokitulppo continued.

GE's new ABXS003 and ABXS005 BoostLynx converters now are available, with pricing beginning at $25.03 and $23.39, respectively, at original equipment manufacturer quantities.
