Hi guys,
I have a design that is very similar to the the one in the demo circuit as per below link
http://cds.linear.com/docs/en/demo-board-manual/dc1929afa.pdf
With my spec being
Vin-170V-350V
Vout24V @1.25A
No secondary sync used
For some reason when I put a load of 5W the voltage is 23.7V and it regulated out the whole input voltage (170-400V)
When I put the load to 10W the output drops to 23.3V and it regulated at that through the whole input range
What could be causing this output drop? Feedback?
