1 Recapturing Lost Space from Mechanical/Thermal Restrictions SlimLynx* & Dual DLynx*

2 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. 2

3 1 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. 3

4 2 Mechanically Constrained Power Single Output Module 4mm* 4mm* 4mm* 12.2mm 12.2mm 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 or any power capacity. PDT012 PDT012 4mm* 12.2mm 4mm* GE Critical Power now offers the Dual DLynx Series as a viable solution to eliminate the clearance between two independent power supplies. These are nonisolated Point of Load (POL) DC-DC board-mounted power module products, offering an industry-leading 25% reduction in board space over previous and competing solutions. This innovation includes the utilization of the PMBus interface for digital configuration, communication and control, as well as adaptive voltage scaling for power reduction. 4

5 2 Mechanically Constrained Power (Cont.) The Dual DLynx also incorporates Tunable Loop* technology, which delivers leading current density for a broad range of applications including data communications, telecommunications, storage, industrial, medical, and military infrastructure equipment. These modules combine a high density solution that integrates two lower amperage parts with a significant size advantage to minimize the use of board space. We ve recaptured board space and returned it to our customers, enabling them to increase their design value, while achieving and maintaining definitive cost savings.

6 3 Dual DLynx - The "Negative" Advantages Offers a broad input range of 4.5 volts (V) to 14.4V and a precisely regulated output voltage from 0.51 Vdc(Digital) / 0.6Vdc(Analog) to 5.5 Vdc. Applications Distributed power architectures Intermediate bus voltage applications Telecommunications equipment Servers and storage applications Networking equipment Industrial equipment PMBus digital interface supports a wide range of commands including on/off, trim, margin, power good, rise time adjustment, startup delay and input under voltage lockout. Digital interface also offers output voltage, current, and temperature measurement capability. Tunable Loop technology enables the user to optimize dynamic response to match the load with reduced output capacitance, thus saving space and cost while improving performance. 6

7 3 Dual DLynx - The "Negative" Advantages (Cont.) Synchronization and remote sense make designing for strict noise and set point requirements easier and more accurate. Single module supplies two independent outputs, achieving density higher than two individual modules, saving board space. Using Unusable Space Between Power Modules 25% Reclaimed Board Space Unusable Space Two Single Output Module 735mm 2 Combine TWO Single Output Modules into ONE Dual Output Module Performs in real world operating conditions. Can support 12A at 1.2Vo up to 80 C without airflow. Reduces input ripple by interleaving 180 C out-of-phase when both outputs are operating. One Dual Output Module 550mm 2 7

8 4 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. 8 8

9 4 Mechanical / Thermal Restrictions for Power (Cont.) The SlimLynx power modules are slim, non-isolated dc-dc converters in a low profile mm height. 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. This self-sustaining unit needs limited airflow and takes advantage of the unused back side of the board or the under utilized space under a daughter board. We re doing even more than giving you back valuable board real estate by living in the shadows of previously inaccessible space; we have developed a definitive solution capable of achieving the highest performance and reliability in applications that take on height, airflow and space restrictions.

10 5 SlimLynx - The "Negative" Advantages Applications Distributed power architectures Intermediate bus voltage applications Telecommunications equipment Servers and storage applications Networking equipment Industrial equipment The compact size of the Pico (12.2mmm x 12.2mm) enables it to be used in the tightest of spaces. The Micro model is 20.32mm x 11.43mm. Available also with a fully insulated, encapsulated design, sustaining costs savings. Can be used on bottom side reflow applications because of the low height and weight. Offers a wide input voltage range (4.5Vdc-14.4Vdc) as well as operating temperature range (-40 C to 85 C). Offers a wide input voltage range (4.5Vdc-14.4Vdc) Output voltage programmable from 0.45Vdc to 5.5Vdc via external resistor, digitally adjustable down to 0.45Vdc Offers a wide operating temperature range (-40 C to 85 C) 10 10

11 5 SlimLynx - The "Negative" Advantages (Cont.) Output voltage programmable from 0.45Vdc to 5.5Vdc via external resistor. Utilizes Tunable Loop to optimize dynamic output voltage response. Constant switching frequency. PMBus Digital Interface supports a broad spectrum of features, such as power good signal, remote on/off switch, fixed switching frequency, over temperature protection and alarms for over temperature protection/output overcurrent safeguard (non-latching)
