LightCrafter power supply reference

Hello! I recently purchased a LightCrafter but did not have a chance to try it as the cables are "sold separately".

Where can I find the references that would allow me to purchase the appropriate power supply?

Thanks!

Hello Pierre,

We are currently working with our distributors and other 3^rd parties to ensure a convenient, reliable purchase path for power supplies. In the interim, here are several options:

The power supply from the Pico v2 kit is compatible with DLP LightCrafter. However, we do not recommend increasing LED current beyond 274, as the power supply is rated to only 2A.
Several universal power supplies with the compatible tip are available online. Here are two examples that should work (link and link) – but we have not verified operation with either. In particular,please make sure the voltage/polarity are set properly.
Use a conversion cable that mates to other off-the-shelf 5V wall mount power supplies. Here is an example (link), although we have not purchased/tested it before.

Regards,

Divya

Hi again,

I just checked the links given in 2. and noticed that both of them have a currnt output lower than the 2A minimum specified on the lightcrafter specifications...

Does it matter or should I give one of those a try anyway?

Hi Pierre,

Digi-Key will also be offering a compatible power supply with a higher maximum current output. Digi-Key is now accepting orders at this URL:

Dear Team,

The Digikey supply is currently on backorder until 3/21/12. Do we have any other suggested supplies and sources? We would like to get something this week.

Thank You,

Dear George,

You can acquire a power supply rated at 1.2A from the links mentioned earlier in the same post.

But, you should note that the LED currents should be set at suitable values. For instance, at 20 lumens (setting of LED current to 100), LightCrafter consumes 0.5A. For the same brightness and LED current setting of 274, it consumes 0.7A.

Depending on the DDR memory access by DM365, high speed patterns, increase in lumens, or with the fan on, the power draw increases up to 2-2.5A.

Regards,

Divya

Hi Divya,

I am a little confused here with the power supply for the LightCrafter. The links you have posted have variable voltage but max current of 1200mA. However, according to the DLP® LightCrafter™ Evaluation Module (EVM), "Power supply: 5-V output with 2- to 3-A current rating" is required. Is the current component not important? Please advice.

Thanks

Hi Bharat,

Welcome to DLP & MEMS Section of TI E2E Community!

Sorry for the confusion. The output current rating is important. You can purchase the LightCrafter power supply from Digi-Key, http://www.digikey.com/scripts/dksearch/dksus.dll?vendor=0&keywords=t1212-p12p-nd
