We are looking for an engineer to help build, layout a VCCC (Voltage Controlled Constant Current Source) Power supply. We have older documents and past projects but are looking for a simple, 5-10A circuit, small as possible. The Set constant Current shall be linearly controlled by the 0-5V input voltage. Similar to attached. Deliverables shall include Schematic, Layout and some sort of proof-of-concept test. We need to know it functions as required. There will need to be multiple potentiometers, one for setting maximum current, one for threshold (minimum current) and another for 0-5V scaling(i.e. if input voltage is 0-4.5V, rather than 0-5V)
