12V TO 5V DC DC Converter 

Question: Step down & Boost & Automatic Step down and Boost DC-DC Converter
Answer: 1. Step down DC-DC Converter- Input voltage must be more than 3V output voltage 

               2. Boost DC-DC Converter-- Input voltage must be less than 3V/more of output voltage
               3. Automatic Step down and Boost DC-DC Converter-- output voltage between the input voltage range

Question: Can you customize multi-output 12 to 5v dc dc step down power converter ?
Answer: For now, because of the Yucoo dc dc converter’s design and it’s capacity, we can make 2-channels as max output.

Question: Can you make the 12 to 5v dc dc step down power converter with adjustable output voltage?
Answer: NO. We can only make stable output voltage mode.

Question: Can you make the 12 to 5v dc dc step down power converter with stable output current?
Answer: NO. We can only make adjustable output current mode.
For example : one 0-10A model dc dc converter, if you connect with right load, all things will goes well.
                       No need to make stable output.

Question :All of your dc dc step down power converter is the same appearance?
Answer: 1. The material has two different kinds: Aluminium and plastic shell
               2. This two materials converter each has three kinds: large size,middle side,small size .
                  different output power has different shell

Question: Does all of the dc dc step down power converter with anti interference filtration and TVS(1500w) function?
Answer :All of the dc dc step up power converter with anti-interference filtration and TVS(1500w) function.

Question: Isolated & Non-isolated dc to dc converter?
Answer: 1,isolated dc converter is no any interference, it is suitable for sophisticated equipment and there is no any ripple
               2, Non-isolated dc converter with ripple.
               3, Dc dc converter we design is non-isolated.

Question: What is the different between the PCB and the Aluminum case type?
Answer: Both are waterproof but PCB case type with light weight.

Question: Can you make the dc to dc converter with adjustable output voltage?
Answer: No, we can just make it stable output.

Question: What is the biggest power for this small size dc to dc converter now ?
Answer: The biggest power for this kind product is not more than 360W.

Question: All of your dc to dc converter is the same appearance?
Answer: 1,The material has two different kinds: Aluminum and Plastic shell.
               2,This two materials converter each has three kinds: small size, middle size, large size. Different output power has different shell.

Question: Does the dc to dc converter support running in full load?
Answer: 1, No, all of the dc to dc converter did not work in full load.
               2, The efficiency small or equal 80%.
               3, For example: Model YK-DD12S2412 12VDC-24VDC 12A dc converter, it can support running 240W*7*24 hours.
