Introduction:In today's system design, design cycle time is very short. In many cases, power supply design is put as the last task and PCB space left behind for power circuit is very limited. This issue can be solved by the LMZ-series of power modules introduced by National Semiconductor. SIMPLE SWITCHER Power Module series is an enhancement of the highly successful SIMPLE SWITCHER® family; the new series has a higher level of integration and user can experience new meaning of "ease of use".
The power modules provide the efficiency of a synchronous switching regulator with the simplicity of a linear regulator, eliminating the external inductor and complex layout placement challenges typical of switching regulator designs.
Besides explaining the features of SIMPLE SWITCHER Power Module, this web seminar will touch on the new WEBENCH Power Architect design tool. The enhanced WEBENCH Power Architect enables engineers to rapidly create multi-output DC-DC power supplies for an entire system. SIMPLE SWITCHER Power Module & Power Architect works hand in hand to tackle any power issue from concept to prototype in unprecedented short period of time.

Introduction:With less capital available for continuous system "upgrades", new data center solutions must be flexible and energy efficient to support the multi-faceted expansions to keep ahead of users data storage needs. Engineers are leveraging open industry standards like PCI Express (PCIe) and SAS/SATA, to create cost-efficient architectures which address current and future data center requirements. In this webinar, we are going to discuss the key concerns that system designers face while designing high-speed interconnects and the solutions that can support PCIe 2.5/5.0G and SAS/SATA 3.0/6.0G. National Semiconductor is ready for the future system requirements.

Introduction:Dimming of LEDs can extend the lifetime even further and also reduces power drain. Today’s TRIAC phase-control wall dimmers are designed to interface with pure resistive load, such as incandescent or halogen light bulbs. Since an LED bulb does not appear as a resistive load to the TRIAC wall dimmer, dimming an LED bulb using a conventional TRIAC wall dimmer does not yield good dimming performance. In this Webinar, we will discuss in detail the challenges of LED dimming with a conventional triac wall dimmer and how National’s new triac dimmable offline LED driver overcomes the issues and achieves full 100:1 range of uniform, flicker-free dimming. This solution enables truly direct LED light bulb replacement of existing incandescent or halogen bulb systems connected to standard TRIAC wall dimmers.

Introduction:Most of the telecom systems today contain on board high performance processors, FPGAs and ASICs. A cost effective solution that can drive these systems while delivering high current levels at low output voltages, fast transient response and tight regulation is in high demand. All these requirements raise the bar for the next generation power distribution architectures (PDAs), which in turn inspire evolution of new technologies. This seminar will discuss the evolution of PDAs, as well as key features and technical details of several power distribution systems. It will conclude with market share predictions of different PDAs for the next 5 years.

Introduction:Along with larger data communications capacity, and limited by BTS space, power density requirement in telecom power module has increased dramatically over the past few years. Half-bridge with secondary synchronous rectifier is an effective power topology to improve the power density. It can help minimize the transformer size, decrease the output inductor size and offer many advantages compared to active clamp topology. However, there are also challenges in designing with Half-bridge. This seminar will discuss the advantages of Half-bridge topology and provide solutions to the design issues.

Introduction:As mobile technology evolves, base stations are required to provide much higher data rate and voice capacity. All these demand higher performance signal path solutions and, at the same time, energy efficiency. National Semiconductor has ample experience with these requirements, having provided a wide range of high performance signal path solutions for wireless base station (BTS) in 2G, 2.5G, 3G and 4G systems, including data converters (ADC and DAC), high-speed amplifiers, timing and clocking, and power management. This seminar will discuss the new system requirements and its implications to component selection.

Introduction:To build a high performance industrial system, precision products such as low offset operational amplifiers and high resolution ADCs are used to improve the signal input from transducers to the digital core. While the signal quality is important in these systems, the market is also demanding systems with less power consumption and higher reliability. This webinar will discuss how to optimize the power hungry signal path to achieve reduced power consumption, high precision and reliability.

Introduction:TCA and uTCA are getting popular in today's infrastructure systems. We see an increasing number of designs with bus supporting multiple daughter cards. The first Hot-swap control chip was introduced to reduce the inrush current when plugging a card into the backplane. Now, the hot-swap technology is far more mature.
In this seminar, learn how to control hot-swap reliability, stability and overall cost with your backplane control scheme in this seminar. Also, find sample waveforms that demonstrate how intelligent current-power limit combined technology helps with hot-swap interface design.

Introduction:There are many misconceptions around Fractional N PLLs. One of them is that they require different design equations and simulation techniques that are used for integer N PLLs. In fact, they use the same concepts and equations. The difference, though, is the performance. By having smaller N value, Fractional N PLLs theoretically have better phase noise performance. Although Fractional N PLLs contain compensation circuitry for the fractional spurs, typically it is still a net improvement. This webinar will address some of the misunderstanding of fractional N PLLs, introduce the advantages and disadvantages of fractional N PLLs over integer N PLLs, fractional N PLL design consideration as well as design tricks.

Introduction:National solves power management design problems in space- and energy-constrained applications, from feature-rich handheld devices through large line-powered systems. From the novice power designer to the power expert, National's products, people and design tools enable customers to design energy efficient systems with complex power supplies in the quickest time. The latest offering is from National's high-performance switching regulators, the SIMPLE SWITCHER^® family. In this seminar, attendees will be shown the new features added to this family and how these new technological advances will help engineers solve their design challenges. At the same time, the complementary Webench design tools that enable engineers to finish prototypes online will be demonstrated.
