With a footprint of just 25.4mm x 12.5mm, the non-isolated unit offers two independent and configurable 40amp, 100W outputs.
Artesyn Embedded Technologies has released the LGA80D DC-DC module, which offers one of the highest current density ratings in the industry and market-leading efficiency of 95.5 per cent typical.
With a footprint of just 25.4mm x 12.5mm, the non-isolated unit offers two independent and configurable 40amp, 100W outputs, which can also be combined to a single configurable 80amp, 200W output, according to the company.
Design engineers can also generate higher current rated rails by connecting up to four units in parallel so that up to 320amps can be supplied as a single power rail. Both analogue control and digital control functions are enabled on the unit, so the LGA80D can be controlled with resistors or controlled and monitored by using the industry-standard PMBus digital interface.
Applications such as graphics, data or video processing, using high power devices, such as server processors, FPGAs, supercomputers, network, storage and telecom equipment, can benefit from the current density, efficiency and flexibility of control of Artesyn’s LGA80D digital DC-DC converter.
"The key is to increase the amps per square inch current density of non-isolated converters with the objective of freeing up space that can be used to increase the computing power of a board by reducing the amount of real estate used for power conversion. Adding one square inch can make a significant difference, with the released space available to be used for additional processing functions," said Andy Brown, DC-DC technical marketing director for Artesyn Embedded Technologies.
The input voltage and output voltage specifications remain the same in any configuration, so the input is defined as 7.5V to 14V and the output voltage can always be adjusted within the range of 0.6V to 5.2V meaning that a broad range of semiconductor devices and applications can be supported.
For simple evaluation, configuration and monitoring, Artesyn offers a PC-based graphical software package in conjunction with an evaluation kit. Two intuitive tabs allow developers to enter the required settings for individual converters and monitor the status and parameters.
The demonstration board is fitted with two LGA80D modules allowing design engineers to test independent channel, or stacked-module operation.
