Questions answered in these manuals
What is the maximum switching frequency limit for the FAN9611/12?
The maximum switching frequency is clamped at 525kHz to guarantee stable operation with less switching loss at light load.
What is the minimum switching frequency requirement for the design example?
The design specifications require a minimum switching frequency that is higher than 50kHz.
What is the typical output voltage for universal input PFC designs?
The appropriate output voltage selection is about 400Vpc.
From: FAIRCHILD AN-8021 Manual
Why is changing the reference voltage preferred over modifying the feedback divider?
Changing the reference has no effect on loop gain and does not affect over-voltage protection levels, unlike modifying the feedback network.
From: FAIRCHILD AN-8021 Manual
What is the non-latching output OVP trip point?
The non-latching output OVP trip point is set at 108% of the nominal output voltage.
