Tool/software:
Hi Expert,
We are verifying TAC5815 spread spectrum feature in customer board, Fsw = 768KHz , and found that after we adjusted RAMP_SS_CTRL1 register TRI_CTRL value, the power of speaker will change,
RDM_EN =1, TRI_EN =1
Fsw = 768KHz ,TRI_VALUE = 0x0f, the power of speaker is 10 W, TRI_VALUE = 0x03, the power of speaker is 7.5W
Could you help analysis why TRI_CTRL value will impact the power of speaker?
