These products, which range from standard linear regulators to switching regulators to power supply controllers to plug-in and integrated power solutions, are tailored to meet design challenges in every segment. And, TI makes designing easier by providing leading-edge support tools such as training, a broad selection of evaluation modules (EVMs), application notes, comprehensive technical documentation and more.
During this webinar Brad wish to give you an overview of TI’s power products and introduce new power management products ranging from power supply controllers to DC-DC Converters to digital power controllers to High power PoE controllers with special features.

NXP recently released the industry's fastest ARM® Cortex™-M3 based family of microcontrollers, the LPC1700 series. Running at speeds of up to 100 MHz, LPC1700 microcontrollers are 28 - 64% faster than comparable Cortex-M3 microcontrollers available on the market today.
During this Webinar, I will provide an overview of the LPC1700's key features and benefits, enabling it to offer best-in-class performance. I look forward to your participation.

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.

NXP has over 10 years of experience in Class D amps. We offer a broad range of amps for low-, medium- and high-power applications with specially developed features that ensure robust performance, and bring exceptional value by reducing external components and offering pin-to-pin compatibility for greater design flexibility. During this Webinar I wish to give you an overview of NXP's Class D amps and the special features which help to differentiate our products. I will also introduce several key amps within the range to highlight their characteristics in low, medium and high-power applications.
I invite you to join me for this webinar as I showcase the benefits and usage scenarios of NXP's Class D audio amplifiers.

This seminar will discuss on what are the different uses of the Guard Output. When you attend this web seminar, you will understand the purpose of Guard in the Triax cables. Also you will learn how to use Guard in test fixtures and obtain fast output voltage readings from high output impedance devices as well as how to measure resistance values of components without removing them from the PCB.

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.

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.

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.

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.
