VF = Forward voltage drop of the output rectifier. The following power supply characteristics must be chosen: 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 IO. Vripple(pp) – Desired peak–to–peak output ripple voltage. In practice, the calculated capacitor value will need to be increased due to its equivalent series Vripple(pp) – resistance and board layout. The ripple voltage should be kept to a low value since it will directly affect the line and load regulation. NOTE: For further information refer to Application Note AN920A/D and AN954/D. |Vout| + 1.25 1 ) R2 R1 |
