I'm using a 555 in monostable configuration to trigger a relay (which will control a 120W load), but I noticed that the output voltage is greater than input. Am I missing somthing here or is this some sort of bug?
P.S. When I remove the relay, I get the expected ~10.5V
Update: It's the resistive load that's causing this. At 15ohm you get extreme output voltages (KVs) and sometime it simply can't solve the circuit. At very low resistance (replaced the relay with a resistor) things get crazy and current flows backwards.
Maybe it's related to the fact that a 555 shouldn't be handling so much current
