Intro
Its been the holiday week all last week with Diwali and stuff and family gatherings and such hence the delayed post. My focus has been on the shopping list since it usually takes LOOOOONG to get the needed parts and I have been successful in placing the request for samples from Wurth. The e13 shopping list is a different story altogether. Lets see if I can log this right.
A bit of background and progress report
My design uses the TPS92512 to drive a bunch of LEDs and the intensity is controlled via a CC3200. The objective is to have an RGB light that can replace commercial lighting. To bring down voltages to usable levels, I need an SMPS. No I will not be designing on because its a Design Challenge on its own BUT I will be doing something about that since I have long needed my own SMPS design. Hence I need an SMPS which does not fit into my budget from e14- therefore...Bought-out.
The Extra Bits
Additionally, I will be designing a PCB for the TPS92512 and the LEDs as well. I will getting it manufactured from seeedstudio’s Fusion service during the holidays. Still working on that part. The passives such as coils and Caps as well as the LEDs I can get from WE. I was able to get the sample request out to Wurth and I got a call from FedEX the third day of the email. That’s mind bogglingly fast! Kudos to the guys at Wurth Electronics for getting them shipped so fast. Brilliant!
Shopping from E14
I need a long list of parts such as the TPS92512 and some other LEDs which were not available from WE(Agricultural Grow lights types LEDs) and since I do not have a reflow soldering oven, I though I would make one so I need the parts for that as well. Next I thought I would get a BTLE solution just in case I wanna go from CC3200 to something else BUT the TI solution is just TOO expensive. I have some issues with placing an order request with element14 which should get resolved pretty soon as well.
What next?
I need to test out the PWM functionality with the TPS92512 as well as layout the PCB. This I need to fit into my freakishly busy schedule in the next week and I will prolly have a video in the next post for the unboxing of the parts I get from Wurth. Along with that I will be doing a description video of Wurth Electronics Kits which I have received in the past as a part of previous design challenges. So essentially my next post will be dedicated to Wurth Electronics.
So thats it for now. Keeping building
Cheers,
