Dear sir, Please trust and give us a chance to work on this deisgn, my team have more experience on power supply. Please let me introduce a little about myself: 1. I have a team (7 members currently, can increase if need), we are working for a USA company(schematic design and PCB Layout, 3D models). - The software we are using is Cadence Allegro 15.7-16.6.10, Altium 14.3 and Mentor Expedition EE7.9.4. Solidworks 2014... - The board can be small to large: up to thousand components and high density constraint, high speed signals, PCIe, SFP, DDR3...etc. - Multi layers boards. (2 layers up to 40 layers). - Multi people to work on the board to meet your schedule. 2. Working Proceduce: 1/. We will estimate the working time. If you approve the working time, cost, and schedule, we will start to work. 2/. We will send you the daily report to report status and bring up any questions/issues regard to 3D, schematic, layout (block diagram, documents, guidelines, ...). 3/. You can send us any requirement on report daily via g-mail:ducthang2013 4/. Note that we can put multi people on a design so the schedule can be reduce to meet your request. Thanks for your consideration. If you need more information, please let us know.

Dear Valued Employer, My name is Martin Botsov and I am an engineering physicist with extensive experience in the field of circuit design, circuit prototyping and PCB design. As I understand from the project description, you want to have a custom designed DC-DC converter as per all requirements listed in the attached specification. So, without further ado here's how the workflow would look like, if you happen to choose me as a partner for your project: 1. Initial discussion 2. Initial draft based on project requirements 3. Schematic drawing 4. PCB design 5. Production files (STEP, BOM, GERBER, NC DRILL, PICK & PLACE) 6. PCB manufacturing 7. Procurement of components 8. PCB assembly 9. Test and measurement 10. Freight Prototype production is a subject of additional discussion. Don't hesitate to contact me with questions regarding details around your project. I am looking forward to hearing from you soon. Thank you for your time. Kind Regards Martin Botsov

I have designed professionally DC-DC converters, so I am fully familiar with the needs for this project, and I have all the technology options available for you. We would need to review the specifications (which I have looked at) to make sure there is common understanding of your needs. Then we can review the preliminary design based on ideal components, and then look at the SPICE simulation. I would deliver the SPICE file based on ideal components. For this kind of design, the kinds of components used are very important for a successful end-result. We would review the components recommend for layout as well as the expected power consumption and efficiency. Then we would review the simulation. And then we would review the layout. Finally, the final design would be available for review. I would then incorporate reasonable adjustments to provide your final design!
