Hi Team,
We are using UCC28710 controller in the fly-back power supply .The input range is of 110V to 230V single/three phase and the output power requirement is of 60W. We are facing an audible noise from the transformer when the DUT(Device under test) is powered on with load >0.5A and the noise is gradually increasing w.r.t increase in load .Kindly let us know how to troubleshoot and suppress the audible noise.
