Other Parts Discussed in Thread: TAS5624A,
My customer encountered problem below while performing output power measurement:
Setting : PVDD=58.5V, Rosc=30kohm
PBTL mode:
3 ohm load : Vout about 27Vrms, /OTW & /Fault are activated
4 ohm load : Vout about 28Vrms, /OTW & /Fault are activated
5 ohm load : Able to achieve Vout about 50Vrms, /OTW is activated at low Vout too but /Fault remain high.
Questions :
1) Why /OTW is activated at low output?
2) Why /Fault is activated for 3 & 4 ohm load?
BTL mode: (5 ohm load)
Abnormal output signal when output power exceeds 120W
Question : What is the possible cause?
Additional info : Customer is using their current design of TAS5624A circuitry and replace the IC by TAS5634 with surrounding components' value as stated in datasheet.
Thanks.
Best regards,
Chin
