Seeking Your Feedback on a Beat Our Board Design Challenge - Grand Prize $5,000

rscasny
rscasny over 1 year ago

I've been in discussions with a component supplier who would like to sponsor a Design Challenge.

But its vision of the Design Challenge is a little different than how element14 typically administers a Design Challenge. I want to tell you the details below. I would really appreciate you voting in the polls and offering feedback on the challenge. Thanks.

What is the Beat Our Board Design Challenge?

The goal of PI Beat Our Board Design Challenge is for the participants to design a board that improves or beats the sponsor's DER-953 board. Below, I've posted a short video and a schematic of this RDK, as well as the datasheet.

How Applicants are Selected as one of the Top 10

The Top 10 submissions get to advance to the next stage and will be given the DER-953Q plus a $250 shopping cart to buy materials – fulfilled by Farnell. The sponsor or its representatives will judge the finalists. They are awarding $5,000 to the grand prize winner and $2,500 to the 2nd place winner.

The enrollment period will last 6 weeks.

What they need to show to be one of the top 10

To be selected as one of the Top 10, the applicant needs to show the following:
• Topology / switch type
• Transformer size
• Preliminary schematic

The length of the challenge is about 6 months (ends June 2024).

Here are the criteria to win:

• Cannot use InnoSwitch
• Beat the efficiency – 10%, 25%, 50% and 100% no-load
• 40-500 V DC input
• Size/ volume of board must be same size or smaller
• Must meet thermals – 85 degrees Celsius – no heatsink
• No optocouplers
• Component count
• No-load consumption
• Automotive qualified components only
• Transformer exempt
• Up to and no more than a 6-layer PCB
• Specify PCB stack up weight per sq foot- 2oz 1oz 1oz 1oz 2: Maximum copper thickness on top and bottom layers
• Overload power current limit = 8.1 A

What do you think of this challenge? I invite you to offer your thoughts in the comments section below.

I also invite you to vote in the following polls:

    There is a trick or typo in the target spec - PI's board accepts 150 - 500V DC but the challenge is for 40-500V DC. But on to the substance. If I were to accept this task as a commercial project (which…

    It is very cool but too hard, I think. Maybe it is hard just to me, but I think it is very hard in comparison with standard design challenge, when you can take just a Arduino and do something. I consider…

    Here's another idea, just to brainstorm a bit;

    It could be attractive to customers to see the actual use of the PI product, for instance, what it is like designing for that unusual IC package, and what real-world transformer (or custom one) works, and what is practical in terms of PCB size and PCB technologies, and what measurements were taken. This would (I hope) be interesting to the manufacturer too; they could learn a lot since nobody will know their product better than customers who get their hands dirty with it.

    Trying to compete with other manufacturer parts is for sure a valid challenge, but it's a type of challenge that might help in initial device selection but won't help customers in using the PI product.

    Since it's a lot of work, and 10 contestants who will do it justice with the custom work (PCBs, etc that will be required) will be hard to find, perhaps a method without a contest could be better, that way only one person (or say two persons) need to be found, and let them have lots of latitude in what they design, and providing they do produce the material, then for them to be awarded the full amount (it would easily consume a couple of months of work, so instead of June 2024, material could be available sooner this way, and if customers benefit from it, then PI could run a second campaign of some sort - so it's quite efficient. It would cost the same - might as well let both people (if there are two) be awarded the identical full amount if they produce the content; let them not feel they are competing against each other so that they can share material as they work.

    If it were me (I am not saying I would apply, but I might be tempted if I could concentrate on the things that I feel would interest me and customers, rather than try to meet a specification that doesn't meet my needs) I'd be interested in making a reliable power supply (perhaps several of the PI devices, OR'ing them together) with the benefit of higher output current at lower input voltages.

    It might not be what all their customers might want (but I bet manufacturers only know what a subset of customers do with their products; and if PI really wanted precise alignment then they might benefit from looking for a case study with the customers that they might already be working with). So, in this case, perhaps it is not a negative thing that it will be hard to find 100% alignment; if the application is still likely to reveal relevant stuff - for instance, I would say that's quite realistic from a heat generation point of view, having more heat sources on a board than just a single power supply.

    Others might be interested in (say) using the chip for a different output voltage, perhaps, and maybe that might reveal valuable information to customers, about how versatile that chip is (or not).
