National semi LED WEBENCH can assist engineers to screen hundreds of high brightness LED

October 24, 2007, National Semiconductor Corporation Ns (National Semiconductor Corporation) announced the launch of a LED WEBENCH online design tool, can help engineers to quickly screen more than and 200 high brightness LED, and complete system design in a short period of time. WEBENCH design tool can be LED Avago Technologies, CREE, product parameters Lite-On, Nichia, OSRAM and Philips Lumileds and other brands (such as light output, color, size, angle, current and rated power) were compared. Unique "It express" (Build!) feature, can be customized in a short time to the customer's model suite to the hands of engineers. Avago Technologies solid-state lighting products division senior marketing manager Kai-Chong Cheng said: "the need for LED solutions to take full account of the whole system. The design tool LED WEBENCH system of national semiconductor is not only easy to use, but also can match the national semiconductor driver suitable for high brightness LED Avago products, to provide a full range of LED solutions for the system design engineer. "Using LED design tools WEBENCH system of national semiconductor, engineers can be as high as 60 series or parallel connection configuration with LED. Engineers only need to list the selected LED, and then gently press the keyboard design tool LED WEBENCH system will be in the national semiconductor PowerWise high efficiency LED drive many, looking for a driver, a power supply, and the ideal. The engineer enters the required size and efficiency of the design, and then simulates the dynamic characteristics of the circuit, such as start-up, steady state, pulse width modulation (PWM) light dark control and line transients, etc.. After the last tune a few minutes, "modeling express" (Build It!) function will provide users compiled a LED system required by the bill of material, but also can be completed including LED, personal computer circuit board, driver IC and passive components including customer customization model kit. "Using the design tool LED WEBENCH system of national semiconductor and system design engineers can complete the whole design in a very short period of time. Otherwise, it may take several weeks to conduct complex tests. "Cree XLamp, LED director of product marketing Paul Thieken said," in this set of design tools, engineers can easily XLamp high performance LED Cree products selected driver and passive components, and to quickly complete the whole design. "

National semiconductor technology sales and vice president of web design tool Phil Gibson said: "according to the survey of customer comments show that LED WEBENCH system design tool design can save 32 hours for engineers in the selection of components, circuit design and design of power system etc.. In fact, it is impossible for an engineer to do only one thing in the first four days from morning till night, so that the workload is equivalent to a few weeks of work according to the normal work schedule. National Semiconductor's LED WEBENCH system design tool allows engineers to accomplish these things in a flash. "This LED WEBENCH system design tools and other national semiconductor WEBENCH design tools collocation used together, including design tools can support power management chip, signal path design, audio system, amplifier and filter and the national semiconductor" simulation technology "(Analog University) to provide university online courses.
