Does my DROK 12v/5v stepdown converter SR Adjustable DC 8-22v to 1-15v 3Amp regulated power supply draw any current from the input battery when the output side is open circuit
(disconnected) Thank you a reply would be appreciated.
I have the LM2596 with the 4 button adjustment. There is no led indicating input or out put. But I can assume the batteries i have is reading correctly. But the output ( and the issue I am having) is that i can hit the + / – buttons but it doesn’t hold to the voltage I want and goes back to 00.0
