Part Number: TPA3110D2-Q1

Dear all,

Could you teach me about title?

At 16V/14V/11V/9V, how does the temperature characteristics of GVDD change?

You mentioned that GVDD will change 6.4~7.4V at Vcc=12V/24V at data sheet.

In other words, will not the temperature characteristics of GVDD change according to Vcc?

Best regards,

  • Hi Yamamoto-san,

    According to our experience, the variation of GVDD across temperature is less than +/-1%. In the application, GVDD is basically used for PLIMIT. You don't need to worry about the precision of GVDD, it won't be the bottle neck.

    Dear Zheng-san,

    Your comment means that we should only treat the variation of GVDD as 6.4V~7.4V at data sheet.

    Is this my understanding correct?

    In addition, does the voltage of VCC have naught to do with the variation of GVDD?

    Best regards,

    Hi Yamamoto-san,

    The variation of GVDD is within the spec. GVDD is from a high precision LDO, so in theoretically the variation of GVDD is not related to PVCC.
