Recapturing Lost Space from
Mechanical/Thermal Restrictions
SlimLynx* & Dual DLynx*
Today’s Power Hungry Landscape
As the demand for increased capacity continues to escalate, designers are constrained when imagining tomorrow’s
possibilities. Utilizing traditional methods and aging technology, the need for a new standard has become paramount.
At GE Critical Power, we’ve introduced a revolutionary concept, “Designing in the Negative Space”, that will
forever change the landscape of design and unleash creativity. We’ll examine two core challenges that currently
plague today’s industry and introduce a full line of innovation to feed specific issues in power-hungry designs.

What is
“Negative Space?”
So what is “Negative Space” exactly?
It is the unclaimable, wasted, or inaccessible
space on a board or a chip. Whether it is created
by mechanical or thermal restrictions, serves as
a power channel or is claimed by other functions
(such as management or support), the end result
is the same; it cannot be used. Until now.
GE Critical Power discovered how to fill the
void. We absorb content or circuitry in order to
reclaim that wasted space. We’ve looked at the
functionality of our power supply to see how our
designs can enable a new standard of power.
So, what led us to this “negative” way of thinking?
There were two significant issues our customers
faced for which we developed revolutionary
new products to help them move forward.

In this classic scenario, a customer needs two
dedicated power supplies to meet the requisite design
requirements. Based on this usage, it is very easy to
note the necessary (and wasted) clearance between
the power components. 4mm of space. This restricted
area has traditionally been off limits to design features

Mechanical / Thermal
Restrictions for Power
Right now, the networking, storage, and wireless
industries are forced to make design concessions
as the need for increased power densities grow.
Designers have to allow more dedicated space for
computing and value add features.
Until now.....
The GE SlimLynx can be placed underneath the
mezzanine, or middle level, making the low height area
of the main PCB usable for power.
This compact, low-height packaging also allows
mounting near, traditional heat sinks, conserving both
space and managing thermal challenges.

These modules operate over a wide range of input
voltage and provide a precisely regulated output
voltage from 0.45 to 5.5Vdc, programmable via an
external resistor and PMBus™ control.
