National Semiconductor’s LED WEBENCH Tool Helps EngineersBy National Semiconductor
National Semiconductor Corporation's light-emitting diode LED WEBENCH® online design environment helps engineers select from and design with more than 200 high-brightness LEDs in minutes. Products from Avago Technologies, Cree, Lite-On, Nichia, OSRAM and Philips Lumileds are compared across multiple parameters, including light output, color, footprint, viewing angle, current and power rating. A unique ‘Build It!’ feature ships a custom prototype kit to the engineer within 24 hours. Engineers can configure a system with up to 60 LEDs in serial or parallel strings. With a single keystroke, the LED WEBENCH tool matches an LED with one of National’s PowerWise® energy-efficient LED drivers and creates an optimized power supply circuit. The engineer can easily “dial-in” their size and efficiency requirements, and then simulate the circuit behavior under dynamic conditions, including start-up, steady state, pulse-width modulation dimming and! line transient. After fine-tuning the system in just minutes, the ‘BuildIt!’ feature provides a complete bill of materials for the LED circuit and the ability to quickly ship a custom prototype kit containing the selected LED, PC board, driver IC and passive components.Blog Posts

- Dev Tools Go By Many Names - Here's Help on Figuring Out What You Need
What do the names starter kit or demonstration board or development tool mean? The fact that there is no strong consensus among tool vendors doesn't help. What's really needed to get started? As someone who has been working in this business for more than just a few years, I will try to help you sort some of this out. - Posted by
