I have a high capacity battery (8.5Ah and 3.6V) and need to supply a solenoid with 7V 400mA with this battery. So I need a dc dc boost converter (step-up converter) to do this. What I want is the schematic of this converter circuit. The IC must be efficient.

NOTE: If you're short of budget, please don't waste time in reading my proposal. For the top services I provide and the excellent quality of my work the bid amount is NOT negotiable. ============================================================ Dear Hiring Manager, I am a professional electrical engineer and have made more than 150 projects for local and international clients. I have also completed 50+ projects here in freelancer.com. You can have a look at my profile and read the wonderful reviews about me. Regarding your project, yes I can perfectly design the converter for you. Please elaborate what do you actually mean by "schematic"? Some students think of it just as a circuit diagram, for others it has a broad meaning and they include calculations of circuit components and coding as well. Please clearly state your requirements. And also please elaborate on this as well "The IC must be efficient.". I try make it clear for you that, for the mentioned bid amount, my deliverables will be: 1- Complete circuit design with calculations. 2- Complete schematic diagram. 3- Complete coding. 4- A very short descriptive report for your better understanding about the project design (for professional report to submit in thesis form etc. I charge $10/100 words). 5- Bill of materials. 6- Free support up to 15 days after the completion of the project. If you want to get software simulation (on proteus/matlab/orcad etc.) I will charge you an extra amount of $100. Regards. Faraz Ahmad

Hi, Many years experience in electronics design, much of it in powersupply design. I assue you are using a LiPo cell and using it to drive your solenoid? How will the solenoid be switched? Do you want a surface mount desigh or all through hole (thru is getting hard to do these days). Did you want a PCB design for this voltage converter f so in what CAD package? I can do Altium and Eagle. Note: you are drving an inductive load so check to see that the solution you select includes provision for back EMF and inrush current. Regards and good luck with your project. James Harrison-Smith
