Tips: What factors affect the output voltage of a DC buck converter?
The output voltage of a buck converter is affected by many factors. The first is the change in input voltage, since the output voltage is usually proportional to the input voltage. The second is the change of load, because the increase or decrease of load will cause the output voltage to fluctuate. The characteristics of the inductor and capacitor also affect the stability and ripple of the output voltage. The conduction loss and cutoff loss of the switch tube and diode will also affect the output voltage. In addition, temperature changes can also affect the stability of the output voltage because the characteristics of the device may change with temperature. Taking these factors into consideration, designers need to make reasonable selections of components and design parameters to ensure the stability and accuracy of the step down converter's output voltage.
