Hi ,
In the TPA20154D1, when the volume was increased, the Vout output voltage temporarily dropped to 0V. When checking other pins, the following phenomena were observed. Does this mean that the overcurrent protection function was activated and then automatically recovered?
-
Switching at the SW pin temporarily stopped, and the PVDD voltage dropped from 5.5V to 5V (PVDD and PVOUT are connected through the circuit pattern).
-
The VBAT pin did not show a voltage drop.
-
The Vin pin temporarily lost its amplitude and settled at the mid-level potential.
-
The Vout pin temporarily lost its amplitude and dropped to 0V.
-
The above “temporary” conditions recovered approximately 5 msec later.
Thanks a lot.
