Hi PMU Team,

In the TPS65250 datasheet, reference design details given on page number 24, fig 40 is not quite clear.

Can you please provide us some reference design having 5V input and 1.0, 2.5 and 1.8V output?

Thanks and Best Regards,

What would be the reference design for the case of not using the dying gasp at all?

Do the 32, 33, 34 and 35 pin will remain open or any of them would have to be grounded?

Thanks

Why don't you try TPS65251 which can support only three DC/DC, without pump mode, exactly p2p TPS65250. if really need TPS65250, please connect pin 32,33,34 to Vin and Pin 35 floating

Thanks. Finally, I am using TPS65251. Very nice to know what to do with the specific pump mode pins for the case TPS65250 had to be used in the future.

Best regards,

Gabriel
