The functional characteristics of Capacitive mTouch^™ Sensing Solution along with basic touch sensor construction will be reviewed in the first half of this web seminar. The primary focus here is to provide some basic design guidelines relating to touch sensor pad size, placement, cover plate material selection and mounting recommendations. In the second half, there will be an overview of the fundamental components of an Inductive mTouch^™ system. It will also introduce the inductive touch sensor detailing both construction and operational characteristics. Inductive touch sensing technologies can make up for some deficiencies of capacitive touch sensing solution. For instance, there can be more choices of panel material, the keys are unaffected by water droplet, humidity or liquids; and the technology can sense through thick gloves.

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.

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.

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.

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.

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.

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.

As Lumens per Watt of LED is continually increasing, high brightness LEDs are widely adopted in today’s automotive lighting applications. Today, almost all interior and exterior lighting applications, even headlamps, are transitioning to LEDs.
Automotive lighting design engineers are now challenged to ensure high reliability, longer life span and optimal performance of the LEDs. An effective LED driving solution is crucial to achieving these targets. In this seminar, we will discuss the technical requirements and challenges for designing automotive LED lighting applications and how the latest PowerWise® LED solutions offered by National Semiconductor help overcome such challenges.

Since the very beginning of Switching Mode Power Supply, controller type solution with separated power switching devices means higher flexibility but much more design efforts. Not to mention the part of complicated loop compensation modeling and calculation. National Semiconductor's brand new constant ON-Time based Emulated Ripple Mode (ERM) regulation scheme provides an extremely cutting-edge and simple solution to design an efficient medium current step down power converter. This technology combines no loop compensation requirement, high efficiency, constant switching frequency, and stability over wide load range. In this presentation we'll be talking about how ERM works and how it benefits system hardware engineer's design with our new online design tools.

Have you ever had trouble designing a new sensor? If so, don't miss the chance to learn how to easily compare hundreds of sensors and complete your sensor path design with National's new online tool. In this webinar, we will go through a new tool with three simple steps: learn about and explore sensors, compare and select the best sensor for your application, and then design and build your solution. We will also share with you design tips and considerations that will support your time-to-market plans.
