Apoorv Posted December 25, 2015 Report Share Posted December 25, 2015 We need three voltage levels +5V , +12V and 24V from a +24V battery.For this we have two LM2596 DC-DC converters. They are operating excellent individually. But when we connect them in parallel, they tend to short circuit the supply.It would be very helpful if you can help me solve the problem.

audioguru Posted December 25, 2015 Report Share Posted December 25, 2015 With the inputs in parallel then they work perfectly. Did you connect the outputs of two in parallel? Why? The output of one has a maximum current of 3A. If you need more current then you need a more powerful circuit. You also cannot connect the output of the 5V one in parallel with the output of the 12V one. Quote Link to comment Share on other sites More sharing options...
