Pcb Power Supply

Pcb Power Supply


Project Board and PCB?

I have a stepper motor circuit resulting in energy projects,. Circuit will not work with a single supply. (+5 1A), however, on the same circuit. PCB does not work with the same power supply needed two different materials. (+5 1A, 500mA and +5), 5 1A supply will be used as a supply of motors and +5 500mA is used for the circuit, I want to know why and how to solve this problem.

Have a good reason for the two devices, even if pressure is the same. stepper motor driven by a pulse with very high. DV / dt (due to the MOSFET switch, which is normal for this circuit). So when you open the driver every motor produced sharp surge. Voltage and negative voltage spike experienced the same small size big enough to confuse the logic of your driving. In theory, you can power both from the same source. However, in practice. You will find very difficult to control circuit voltage that you want to clean, while the driver is causing the power source to vibrate. The best way to do it. Supply it with a single resource that has more capacity. (Hard) than what is sufficient for the total load,. And then is filtered by the device. High frequency, which is placed carefully on the circuit to maintain a minimum of LED, it is often cheaper than two smaller products.
