The module has a footprint of just 1 x 0.5 inches or 25.4 x 12.5mm, and this non-isolated unit offers two independent and configurable 25 amp, 50 watt outputs, which can be combined to a single configurable 50 amp, 100 watt output. Design engineers can also generate higher current rated rails by connecting up to 4 units in parallel so that up to 200 amps can be supplied as a single power rail.
A low-profile variant that is just 0.23 inches (6 mm) high can be used for height-constrained applications, such as compact 5G wireless network nodes. Other suitable applications include: graphics, data or video processing, using high power devices, FPGAs, supercomputers, network, storage and telecom equipment.
The input voltage and output voltage specifications remain the same in any configuration, so the input is defined as 7.5 V to 14 V and the output voltage can always be adjusted within the range of 0.6 V to 5.2 V meaning that the LGA50D digital dc-dc converter can support a broad range of semiconductor devices and applications. It also supports both analogue control and digital control functions, so design engineers can control units with resistors or control and monitor the converter modules using the industry-standard PMBus digital interface.
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 LGA50D modules allowing design engineers to test independent-channel or stacked-module operation.
Artesyn’s new LGA50D series dc-dc modules are compatible with the company’s 80 amp LGA80D series, offering equipment makers scalability with a common fit, form and function at different power and current ranges.
