I have a DC DC energy harvester - boost IC. For this IC the VIN should not go beyond 5.5V. So I hooked up a 5.1V zener on its inputs. I do not know if I am doing this right. As per the zener connection
diagram the zener's cathode indicated by the black line should go to VIN + and the anode should go to VIN-. I did this but when I apply the voltage at VIN to the DC DC boost I do not get the output but when I disconnect the zener I get voltage on VOUT of the DC-DC boost. Am I supposed to use the zener in the reverse? Why is this happening when I connected the zener the right way as many circuit diagrams showed in google search results.Please let me know.
