Part Number: TPA3131D2

Hi,

Is it a must for PLIMIT input to be derived from GVDD? Can it be supplied directly from other source?

Thanks.

Hi YY,
The voltage on the PLIMIT pin can be set to control the virtual power supply and then the output power can be limited. You can also use the external voltage, but usually we recommed users to use GVDD or the divider volatge of GVDD.
Bet regards,
Shawn Zheng
