@Nikhil Gupta: It makes designing a LED system very easy and allows for optimizations across cost, space and efficiency.

How long have you been using the tool, and what is an example of a project you used it on?

Have you tried using WEBENCH LED Designer and LED Architect? It makes designing a LED system very easy and allows for optimizations across cost, space and efficiency. These tools can be accessed from Texas Instruments' website www.ti.com.

So it sounds like this category works pretty much like any other with regard to the selection process - engineers go first to brands they are already familiar with, unless they have specialized needs. You point out that testing is important to verify the specs, does this result in longer product development cycles than usual?

From what I have seen and heard, the market splits into two main groups: for standard product and low-medium volume, the designer first looks to aname he/she knows as a credible vendor. If they have something that is a good fit (featgures and price), then they do a deal. For specialized, custom, or high-volume, the designer goes to a less well-known vendor and looks for a unique, tailored solution, and needs some assurance and testimony/references/track record that they can actually design and deliver the part.

Please, add some names of vendors that you know--as I said, my list was not "complete". I welcome your additions to it.

Why have you not mentioned Tiwanese/Korean and Japanese LED driver IC manufacturers/

Sone of their ICs are realy regud and long lasting

Hi Bill - thanks for posting this. Given that the various claims can only be evaluted through hands-on testing, in your experience speaking with engineers is there a default position that they take with regard to what drives they choose to evaluate? IE, picking a driver from a vendor who is providing other components on the board?

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
