Hi
Regarding to TPS562242DRL, during Eco-mode at light loading, switching frequency may drop to 20Hz~20KHz, which can be detect the sounds by humans.
Is there any solution / method to fix this kind of issue? Or anything we can do while design the schematics?
For example, TPS563252 have another part with TPS563257, which FCCM mode at light loading.
The drawback is the efficiency will be worse, but in this way we can prevent the inductor switching frequency detect by humans.
