Hi,
I need help with the part selection for the following requirements.
Universal AC Input 90Vac t0 265Vac.
PFC - 380 DC link @ 200 Watts. (currently using Onsemi NCP1654).
15V @ 0.33A with the same common as the 380V.
24V @ 1A isolated from 380V and 15V.
We are extremely space constrained and need to have the smallest inductors/transformers possible. We use an aux winding on the PFC choke to generate the 15V VCC for the NCP1654 and will need to continue that for any PI PFC part.
Thank You.
