VIN 24V,VOUT 12V,Imax:5A.The output voltage ripple is normal under static load, and there is no howling phenomenon; when 0.5A~3A dynamic load is executed, the inductor has obvious whistling.
When the RT is set to 100K, 200K, 200K, 300K, there is the phenomenon of inductive howling.I would like to ask how to remove the inductance whistling.
