Part Number:UCC28251
Hi Everybody,
please consider the schematics: ( form UCC28251 datasheet on the page 42 )
please notice the current feedback which is sensed by a resistor through a current transformer ( in the primary side ).
does it need really an opto coupler ( U6 ) in addition to the current transformer ( CT1 )?
is it possible to connect the secondary side of CT1 to the ground of the secondary side ( of half bridge ) to eliminate the U6?
Best Regards,
Ras
