Low voltage PFC with LT1249


I have to design a low voltage PFC for my project.

Uac = 24Vrms, Uout = 40Vdc, Pout = 150W,

The MOSFET, the diode the inductor and the capacitor are determined and selected.

(L = 100uH, Cout = 2420uF)


Could someone help me how to determine the passive components for LT1249?

I have been trying to simulate with modified passive components, but the input current does not look sinusoid and the output voltage fluctuates.

Thanks in advance for the help
