Hi,
We are using TPS65266-1 in our design to generate 1.5v, 1v & 1.8v.
Attaching the schematics. Please review and let us know if the discrete values at each output are correct.
L8, L9, & L10 value-2.2uH
Thanks,

Hi Robbi
It seems good. Just one thing to confirm, what is PWRVIA1 to 9?

Hi Ruby,
PWRVIA1 to 9 are the thermal vias to gnd recommended in the datasheet PCD layout fig 51.
And also in the application schematic in datasheet, some capacitors were mentioned as DNI(C4,C5,C14,C15,C21,C25-Referenece fig 33). Do we need to place them as NC's in our design or not required? Pls guide.
Thanks,

Hi Tejaswi
I would recommend that C4, C14 and C25 to be used as the schematic you provide shows. C5, C15 and C21 can be placed as NC's, because if the phase margin is not enough in the HW due to the parasitic parameters, you can add C5, C15 and C21.
