I have LM2596 DCDC module to be used for power conversion of battery voltage 28V (mine is a 50Ah) to 5V
When i usually connect the input terminal wires of dcdc to battery , it gives a spark due to back emf
i wish to know what kind of protection circuit is needed at input of LM2596 to protect itself against this
in my shelf i find only MBRS340 a schottky diode with me, can it help me in protecting against back emf if connected in reverse bais in parallel to input of dcdc ?
kindly let me know simple protection of lm2596 from battery.
