How to select the appropriate power supply for the application?


It is recommended that the selected power supply voltage value be 10%-50% higher than the maximum required voltage. This percentage varies by Kt, Ke, and the voltage drop within the system. The current value of the driver should be sufficient to transmit the energy required for the application. Remember that the driver's output voltage value is different from the supply voltage, so the driver's output current is also different from the input current. To determine the appropriate supply current, all power requirements for this application need to be calculated, with an additional increase of 5%. The required current value can be obtained by calculating by I = P/V formula.
