Do you have the ability to RoadTest Power Integrations TinySwitch-5 RDK-1016?

cstanton

We're looking for a few members to RoadTest a product from power integrations.

Now, this is more of a 'reference design' than a 'demonstration kit', but we often receive requests from suppliers that are like this.

The product is:

26.5 W dual output isolated flyback power supply for appliances using TinySwitch-5 (TNY5073K)

Information and datasheets are available at: https://www.power.com/design-support/design-kits/rdk-1016-reference-design-kit 

With details about TinySwitch-5 at: https://www.power.com/products/tinyswitch/tinyswitch-5

We would likely be looking for a RoadTester that can put it through its paces and characteristics rather than plugging it in and saying "it works". This means we may deviate from our usual RoadTest of 'sign up and you may be selected' and instead go down the path of 'ok, two or three of you are selected and we'll see if we can also provide you with some parts that you need'. (We tend to call these RoadTest Plus or Special RoadTests).

  • mmmmmmm - I see alot of discussion about lab testing-ish parameters - transients, input corner points, output corner points, power quality in, power quality out.

    How about shock-vibration (in transport or operation like in a dishwasher or refrigerator) on a shaker table, or ambient temperature/humidity corner points

    or ambient noise measurements in an anechoic chamber for audible noise  :-)     

    I'm sure there will be some power supply designer in the community that wants to stimulate their intellectual curiosity.

    That's an interesting point - alluding to the numerous other possible tests I haven't thought of. Indeed, it may be of interest, but alas, temperature/humidity control often means an environmental test chamber (anyone with one of those, raise your hand? *leaves hand firmly lowered*). As for the shake table ... I don't have one either, but perhaps those tests are much more valuable when it's been integrated and constructed as per final-production-design rather than on a reference design that hasn't yet been qualified for EMC.

    I suspect that would very much depend on the quality of the flyback transformer's winding and construction, and any sub-fundamental components of the switching waveform that lie in the audible range. But alas, if I had one of those chambers, perhaps you'd find me sleeping soundly inside ...
