Design a 130 watt DC to DC step down converter (Buck converter)

Pagado a la entrega
We are looking for someone who can make us a prototype of a DC to DC converter. The step down DC-DC converter should be able to convert a 240 DC input voltage to 100 DC or 50 DC output voltage. We prefer the output voltage to be around 50 DC, as long as it's cheaper and efficient, if it's not cheaper or the power loss is significant than we are also happy with a 100 DC output voltage. Please, note this is not a "signal buck converter", it's a "power buck converter", we use it with our high voltage solar panels. Therefore, this converter should handle around 130 Watts of power.

Hi, I am a Mechatronics and Control Engineer, I have already worked on a similar project in which the power was coming from solar panels and it is dropped down to 12V in order to charge the battery. For this I used buck converter which worked really fine. I will design the buck converter on my side and will send you a complete working video so that you get satisfied with its working. Thanks.

Hello, what about the size issue?, not important with you?, so it's just cost effective DC-Dc buck converter?
