Design Formula Table
V
sat
= Saturation voltage of the output switch.
V
F
= Forward voltage drop of the output rectifier.
The following power supply characteristics must be chosen :
V
in
- Nominal input voltage.
V
out
- Desired output voltage, IV
out
I = 1.25
I
out
- Desired output current.
f
min
- Minimum desired output switching frequency at the selected values of Vin and Io.
V
ripple(pp)
- 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.
