Part Number: TPS62866

Hi Sir

1. May I know TI have recommend total solution for RK3399?

2.Reference design use SYR838 and SYR837 for VDD_GPU and VDD_CPUB ,but I saw TPS62866 Vout max is 1.2V ,have any one use TPS62866 for RK3399 ?

Hello Kaile,

TPS62866 can supply up to 1.675V using I2C.

The 1.2V or 1.15V output voltage max you maybe are referring to is the startup voltage.

On the VSET pin is connected a resistor, at startup there will be a readout of this resistor value and this will define your startup output voltage.

See Table 1, to see which resistor is associated to which startup value.

Using I2C communication bus, allow you to supply up to 1.675V.

Let me know if you have more questions!

Thanks a lot.

Best Regards,
Dorian

Hello Kaile,

What do you mean by "what is the platform use of TPS62866"? Are you talking about software to control TPS62866?

I would rather discuss the MP schedule of QFN package version on a private message.

I send you a friendship request so we can discuss, please accept it.

You can start a private message by clicking on the 'chat' icon on the top right of the screen.

Thanks a lot!
