SLLS636N – DECEMBER 2004 – REVISED JANUARY 2015

Typical Application (continued)

9.2.1.1 Design Requirements

The user must determine the following desired parameters:

Vsat = Saturation voltage of the output switch

VF = Forward voltage drop of the chosen output rectifier

The following power-supply parameters are set by the user:

Vin = Nominal input voltage

Vout = Desired output voltage

Iout = Desired output current

fmin = Minimum desired output switching frequency at the selected values of Vin and Iout

Vripple = Desired peak-to-peak output ripple voltage. The ripple voltage directly affects the line and load

regulation and, thus, must be considered. In practice, the actual capacitor value should be larger than the

calculated value, to account for the capacitor's equivalent series resistance and board layout.
