Hi Sir,
We need your help for TPS40210, thanks.
We found PVDD peak current will up to 6A when system power ON PVDD(Boost UP) rise to hit V Switching.
Large current affect will disappear when PVDD=24V.
When system power on, PVDD will drop to 12V (same as VSYS(Vin)) when play music.
PVDD will not go back to 24V even stop play music become light load.
OCP happen as below,
We change current sensing resistor to 0hms ans it will not caude OCP. But will still have peak current.
PVDD have 4*470uF capacitors to following amplifier.
Why boost in load light still have 6~8A peak current? Will it relative with 470uF capacitors?
Thanks, Ian.
