DROK New Designed Buck Voltage Module–Immersion Gold PCB Board

Hi, guys! We may easily purchase cheap but bad module, thus we often suffer from return and waste of time which may easily drive you mad. To solve this, DROK design a brand-new buck voltage module.

To get it with 30% OFF on Amazon:

Amazon.com: https://www.amazon.com/dp/B074FHFKLP    Pro Code: 968YOLLF

This PCB uses Immersion Gold. Well, you may ask what Immersion Gold is. To be specific, Immersion Gold is a coating layer generated through Chemically Redox reactions method and it is a thicker layer, which is one of methods that people usually use for deposition of chemical nickel gold layer. In this way, we could get much thicker gold layer. Advantages of the method are as follow: 1. Crystal structure is more dense and not easy to be oxidized; 2. Nickel gold is only on the soldering of this Immersion Gold board, and the transmission of signal on Skin Effect happens on Copper layer, so signal will not be effected; 3. The combination of solder mask and copper layer on the circuit will be more solid.

We selected high quality components for this module.

As it is well constructed with qualified materials, it will perform better than what you can not imagine. Compared with other normal module, we have a test and here is test result.

Difference of current at no load 
no load no load

Difference of current at stand by
stand by stand by

From the pictures, we could get to know current at no load and current at standby are 7.39mA and 0.311mA. And current at no load and current at standby of compared unit are 12.88mA and 0.82mA. Generally, the smaller the current at no load and at standby is, the less heat the module will generate, then the module will provide more stable output and longer service life.

Difference of conversion efficiency

Difference of ripple at 3A
ri rp

The smaller and neater the ripple is, the purer the output current is. That will be good for protecting load well and better using effect.

By comparison, you will find this Immersion Gold buck voltage module will perform well as its good constructions and selected material.

      Hello rob,
      Thanks for writing in.
      We are not sure the working voltage you required. So far we only have one item can deal with 40A current. You can check if it is suitable.

    Hi, I would like to buy few of these new design buck converters for my next project. I would also like to integrate complete board to my circuit board, my question is, do you have eagle files for this board to show outline and hole placement, so I can import it to my project and later simply solder it on top of my PCB ?

    Thanks

      Hello Nick,
      Thanks for writing in.
      Would you please tell us which item it is?
      We are sorry we don’t ahve eagle files, but factory may be able to show us overall dimensions.
      Best regards.

    Hi, Thanks for your reply, I’ve bought this item, it’s DK-SD15W40V -ADJ v2.0.

    if you can supply board outline with mounting holes and also holes for both connectors,  that would be great help.

    Thanks !

      Hello Nick,
      We are sorry DK-SD15W40V -ADJ v2.0 is not our reference number, is is hard to search item.
      Could you please show us product link?
      Best regards.
