Hello,
I am trying to stabilise the isolated output voltage of this flyback converter.
SCHEMATIC
https://i54.tinypic.com/3162lpw.jpg
It is 5V, 20W at the output.
(Its in CCM)
(it has been arranged to be in Voltage Mode, by a ramp being interfaced to the current sense input of the LT1243)
The input voltage will be 30V to 48V
I can’t seem to stabilise it, and it takes a long time to run.
Can you please help me to get it to run quicker so that I can adjust the feedback components and see if it stabilises?
or help me with stabilisation?
