Terms and Definitions
z
Vsat = Saturation Voltage of the output switch.
z
Vf
= Forward Voltage drop of the rectifier.
The following power supply characteristics must be chosen:
z
Vin= Normal input voltage
z
Vout: Desied Output voltage, |Vout| =1.25 (1+R2 / R1)
z
Iout : Desired output current.
z
fmin : Minimum desired output switching frequency at the selected values for Vin
and Io.
z
Vripple(p-p): Desired peak-to-peak output ripple voltage. in practice, the calculated capacitor value will need to be
increased due to its equivalent series resistance and board layout. The ripple voltage should be kept to a low value
since it will directly affect the line and load regulation.
