Hi,
We want 13V5, 1A5 from the mains (100-265vac)
We dont want to bother with fans, so what say we put a 65w one of these..
FSP065-P24-A19
..into a metal vented enlcosure with no fans, and just change the upper divider resistor so that we get 13V5 instead of 19V?
the feedback loop is likely to be so high in phase margin etc that we can get away with this?
We'd change it so the opto diode etc still got enough current etc.
(I guess as a flyback it may go into CCM at low mains, but we only need it for 200-265vac mainly)
We coudl even adjust the sense resistor so it didnt go into CCM. Since we only need 21W out of it.
