Vsat : Saturation voltage of the output switch.
VF : Forward voltage drop of the ringback rectifier.
The following power supply characteristics must be chosen :
Vin : Nominal input voltage.
Vout : Desired output voltage. |Vout|=1.25*(1+RB/RA)
Iout- Desired output current
Fmin : Minimum desired output switching frequency at the selected values for Vin and Iout.
VRipple(P-P) : Desired peak to peak output ripple voltage in practice, the calculated value will need to be increased
due to the capacitor equivalent series resistance and board layout. The ripple voltage should be kept to a low value
since it will directly effect the line and load regulation.
