TAS5825M: schematic review

Hi  Yasushi Fujiwara,

May i know PVDD voltage for this application? Maximum output power and its load?

On my side, it is suggested to check:

1. PVDD decoupling cap, 4.7uF decoupling cap is not enough. Ti requests for 2*(22uF + 22uF +0.1uF) at least. 

2. Voltage rating of PVDD decoupling cap: it is suggested to be larger than PVDD*1.35V

3.  BST_A/B/C/D cap: it needs to be 0.47uF rather than 0.22uF. Please refer to the latest datasheet.

BR,

Alix

Hi Alix,

Thank you for feedback. Here is answer for your question.
- PVD=20V
- Po=2W@4ohm

I have question about boot-strap cap value. According to EVM, it is 0.22uF. But datasheet mentioned it is 0.47uF. Should customer refer to the datasheet?

Best Regards,
Fujiwara
