I want a step down DC-DC power supply design with 2 different type of prototype. The circuit will work with input power range of 9-70 volt and will switch off the circuit automatically if power goes below 9 volt or above 70 volt. The circuit will give constant output of 12 volt. The current output of circuit is between 1-2 Ampere and input current can be max 3 A
I do not want schematic only. I will need prototype of the circuit (5 piece ) and will test the same for 1 week. If the same works properly, I will request for schematic and once the product made from the schematic given work for 1 week, will consider the project completed. I will prefer someone in India so we can get the material easily and reduce the communication time.
The BOM of the supply need to be below 250 Rs. I will consider the project cost as 100*BOM Cost+Development cost to derive the lowest price bidder.
I like to know your experience with power supply design and prefer who have worked with SMPS and automobile electronics.
