PRODUCTION DATA.
The power supply requirements for the TPA3116D2-Q1 consist of one higher-voltage supply to power the output stage of the speaker amplifier. Several on-chip regulators are included on the TPA3116D2-Q1 to generate the voltages necessary for the internal circuitry of the audio path. It is important to note that the voltage regulators which have been integrated are sized only to provide the current necessary to power the internal circuitry. The external pins are provided only as a connection point for off-chip bypass capacitors to filter the supply. Connecting external circuitry to these regulator outputs may result in reduced performance and damage to the device. The high-voltage supply, between 4.5 V and 26 V, supplies the analog circuitry (AVCC) and the power stage (PVCC). The AVCC supply feeds the internal LDOs, including GVDD. The LDO outputs are connected to external pins for filtering purposes, but should not be connected to external circuits. The GVDD LDO output has been sized to provide current necessary for internal functions but not for external loading.
