Part Number: TPS68470
Hello,
Below is customer schematics. But the power output TPS68470 has no power output voltage now. What register we could configure to let output has voltage? or any setup sequence that can provide to customer. Thank you.

Part Number: TPS68470 Hi,
We should connect both WLED_SW and WLED_GND to ground if WLED function is not used. May we know what is the side effect if the pins are floating?
THanks!

Part Number: TPS68470 Hi,
We are suing TPS68470 in one of the designs. We are seeing PMIC giving wrong output voltages for LDO. If we configure for 1.8V in one of the 1.8V LDO, it gives around 1.4V. it is common for all the LDOs. What might be the issue…
Part Number: TPS68470 Hi,
Customer is not sure if Intel implement SW driver correctly or not for I2C register access. With both I2C_ICA and I2C_ICB connected to GND, they capture some I2C waveform plot as below. From my point, I didn't see anything strange…

What is the requirement of TPS68470 regarding the accuracy of XTAL connected to OSC_IN/OSC_OUT?
And what is accuracy requirement from HCLK_A/B usually?
Thanks!

For the LDO boxed in blow SCH, which will not be used in customer's application, could they just be left floating without adding the output de-coupling MLCC (they have been disabled by I2C registers),
Part Number: TPS68470 Hi,
Some questions as below.
If LDO_AUX2 is not used, how should we connect 3V3_SUS?
If 3V3_SUS is supplied before 3V3_VDD, is there any side effect?
As below, if 5VS is supplied while 3V3_SUS/3V3_VDD is not available yet, customer…
