I need a dc-dc power supply whose output voltage tracks the input voltage with a fixed differential. For example I have 65v in and want the output to be 15v less at 50v. If the input voltages falls to say 50V then the output should fall to 35V and so on. The conversion has to be as efficient as possible into a fixed value resistive load of say 10 ohms. Any ideas anybody?
