Dear Concer
I have designed an isolated supply using LM3485 Buck converter (referance from application note AN-2292). I am using MOSFET SI2309CDS-T1-GE3 & Coupled Inductor LPD5030V-333ME (make - Coilcraft). In put volatge is 24VDC & output voltage is 5.0V isolated & non-isolated.
Issue - humming noise from Inductor LPD5030V-333ME (make - Coilcraft). I caheck for the load of 10mA.
