Hi Team,
As title, Our PSU vendor using modify the CSA/CSB sensing resistors values to improve the input harmonics. To let the power supply can pass the EN61000-3-2 class A at 10%~100% load.
I'd like to learn from TI's point of view, if change the sensing resistors that means change the voltage level of CSA/CSB. Is this design change impact any PFC function? For example OCP percentage? Function? or other input characteristic?
I mean what testing should be verified after the design change? Please TI recommend.
Thank you.
