PMIC IC and power estimation for Cyclone V SoC (5CSE)

Hi all i´m looking for a cost effective supply solution for a custom cyclone V soc board.

I like the TPS65218 PMIC because it´s cheap, this IC haves 4 DCDC converters, three of them are up to 1,8 Amps(DCDC1-3)

and one is up to 1.0 Amps (DCDC4)

My idea is to use DCD1-3 for genrating 1.1 V, 1.2V and 2.5V and DCDC4 for 1.8V for ethernet and HDMI.

Then use a external single buck for 3.3 V and one external LDO for DDR3 and VREF (1Gbyte)

I´m trying to estimate the power consumption for the 1.1 V, 1.2V and 2.5V rails but i can´t find accurate information.

Can someone tell me if the TPS65218 for DCDC 1,2,3,4 it´s the best solution? if not can someone recommend a addecuate PMIC?

May be the TPS659037 ?

It seems strange that the development boards have 3 Amp DCDC ICS for 1.1V HPS and in the power estimator at full 924MHZ and full CPU (Drystone) usage i´m getting 0.7V for the 1.1 V

Thank you so much in advance ;(
