Hi, I am working on project making connection between buck converter and a IOT device which has small battery inside. The problem is the battery inside IOT device giving back current to the buck converter which stops working of buck converter. I need buck converter giving power to IOT device but also need to stop coming reverse current from IOT device to buck converter.
I found some solutions using reverse protection circuit between both. As I know various solutions like PN junction diode, Schottky diode, P-channel MOSFET and N-channel MOSFET. How to know which one is good fit to solve this problem?
And can Schottky diode (20V, 3A) solve this issue?
