Which chip is in this project .. ?

[wissa]

Hi, I came up with this product which I am interested in doing a similar one ... Do you have an idea which chip is in there or could you advise on a buck-boost converter with IN:1-30V and OUT:0-30V if possible with current cabability of 1-2A ??

Here is the link of the product

Greetings,

The controller is a Feeling Technology FP5139 which is used with a NCEPower NCE6075 NFet.
There is also going to be a meter chip controlling the LED display, but those are fairly easy to come by.
I've included datasheets for both chips,

I found a review of board using the  FP5139 https://www.eevblog.com/forum/reviews/30w-sepic-dc-dc-converter-review-(5-35v-in-0-8-35v-out)/
 It's obvious from just the component selection alone that whoever "designed" it, did not have a clue. ON the other hand, it looks like whoever did the ZK-DP2 knew just a little bit more...   

Unlike the other board's 30W rating the ZK-DP2 only has a 15W rating, but it has a lot of adaptability and is not a design from the datasheet(I've only got two though)

I've found out that yes, they still sell them and found an app note which I've also include now.
