UCC28070-Q1 datasheet Pg 35-36 mentions about adding Current sense offset for improved noise immunity. We would like to know whether the Gda input to this is connected from the output of the mosfet driver(Ucc23722/...) or from the GDA output of UCC28070.
In the application note slua479b, Pg 17-18 schematic for 300W PFC pre-regulator design, GDA input - to improve the noise immunity is connected from the output of the driver.
But if we are paralleling the mosfet's and hence the gate drivers there will be two outputs one from each driver. In that case how we can make connections to improve the noise immunity.
