Tool/software:
1. it can work when only connected USB supply with out open PPC3 and connected I2C, it seems that the chip comes with its original configuration and does not require PPC3
2. If I supplied PVDD(We tried 3.4~14V) with J13 and let J20 and J30 open, The amplifier has no output and does not seem to work.
3. If I supplied by VBAT(J30), the voltage of PVDD is always 14V and can not be changed. The amplifier has output but seems at HW mode. (HW mode is the same as the soft mode)
4. If I connected the EVM to PPC3, the output was clipped at around 3W.I tried to configure the EVM board via PPC3, but it did not work.
5. I followed sequence below, but it doesn't work.
- Set SW2 on AC-MB to OFF/OFF to stop the clocks and audio playback.
- Make any required PPC3 adjustments.
- Set SW2 on AC-MB back to OFF/ON to resume the clocks and audio playback.----the current of VIN became ~1.6A and with out output. If repower VIN ,IVIN recover and output recover but seems loss the configuration of PPC3 and just HW mode.
The EVM set up as below:
