Embedded Technologies today announced the LGA50D dc-dc module,
which offers one of the highest current density ratings in the industry. With
a footprint of just 1 x 0.5 inches or 25.4 x 12.5mm, this innovative
non-isolated unit offers two independent and configurable 25 amp, 50 watt outputs,
which can also 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
A low-profile variant that is just 0.23 inches (6 mm) high
is ideal for height-constrained applications, such as compact 5G wireless
network nodes. Applications such as graphics, data or video processing, using
high power devices, such as server processors, FPGAs, supercomputers, network,
storage and telecom equipment, can also benefit from the current density,
efficiency and flexibility of control of Artesyn's LGA50D digital dc-dc
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 Artesyn's LGA50D digital dc-dc converter can support a broad range
of semiconductor devices and applications. The LGA50D supports both analog
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.
