Hi Ryusuke,
GPIO3: If register 0x14 CONFIG2 bit DC12_RST = 0h then GPIO3 can be left floating, I advised to pull up to VP_3P3 in case this was acting as a reset for the PMIC (DC12_RST = 1h) , but if it has no effect, then it can be left floating.

Hello Sarah,
Thank you for the reply.
We are paying attention to that and have powered the board using a power supply with current display, but the board doesn't seem to be using more than 100 mA all together.
I'll send you the schematics and layout…
Part Number: TPS65218D0 Hi,
Customer is using 100KHz I2C to control TPS65218D0.
However sometimes, it is changed to 400KHz and returned to 100KHz.
Is there any issue?
Can customer set I2C speed to 200 or 300kHz non-standard?
Thanks.
Hi James,
James Steenbock said: The configuration you shared should work as you described, although you may want to add a resistor to GND on the AC pin just to make sure the pin doesn't float between GND and some high voltage.

Hi Satoshi,
Do you have another TPS65218D0 chip to test on the board? Can you check to see if another D0 chip shows the ~4ms between DCDC3 and LS1? This might help to see if there's significant variation between D0 chips. Also please send me a picture…
