I am designing a dual output fly-back converter with PI Expert. The design "compiles" with no errors
or warnings. I am outputting 15V and 24V from a 100V to 265 VAC input @ about 100 Watts total.
The RCDZ circuit specified has a Rc2 value of 4.7Kohm but it says there should be 5 of them. (And in the generated
BOM, there are 5 reference designators assigned to them. )
What the schematic does NOT say is how these 5 should be connected (in series? in parallel?). Either configuration
is outside the range specified for Rc2 in application not AN-58.
Which configuration is it?
