Ensure that POutMax can be delivered from the lowest Line voltage for GFF1. Use Equation 17 to calculate the
required Boost inductor value .
(17)
Choose the lower of the two values calculated in Equation 16 and Equation 17 (LBST0 and LBST1). Using a smaller
inductance value compromises light load efficiency. A larger inductance value cannot deliver the required
maximum load power (POutMax) across the required range of Line voltage.
Choose a Boost inductor value of 200 µH, considering a tolerance of 10%. In order to deliver maximum load
power the inductor must be able to operate with a peak current that is greater than both ILPk0 and ILPk1
(18)
(19)
(20)
(21)
Use Equation 22 to calculate a current sense resistance that ensures the required peak inductor current (ILPk)
does not cause early termination of the TON period.
(22)
Achieve this amount of resistance by connecting three resistors in parallel.
(23)
Use Equation 24 to calculate an inductance value that allows a saturation current above the maximum Ocp1
current limit value.
(24)
Maximum current in the power components flows while delivering maximum load when supplied from minimum
Line voltage. In this condition, the UCC28056 controller always operates in transition mode (CrM). shows the
inductor current waveforms for ideal CrM operation.
