PMIC efficiency and selection for DM3730

Other Parts Discussed in Thread: DM3730, TPS65921, TPS65920, TPS65951, TPS65950, TPS65930

Hello,

I'm designing a board with a DM3730 processor and I'm hesitating between several PMIC devices from those listed in http://processors.wiki.ti.com/index.php/AM/DM37x_Overview#AM.2FDM37x_PMIC_Comparison.

I would like to select the best part according to my operating points.

My questions are: for those parts, I can find some efficiency curve in the datasheet, but is there spreadsheets with those data points? Maybe a simulation tool?(Are those products supported by webench?)

Regards,

Thibault

Hello,

I know there is thousand of other posts, but does someone have any sharable information/advice of this subject? I suppose I'm not the only one to raise those questions, but few answers found.

Thanks.

I thibault,

Only curves are available and these devices are not compatible with webench.

TPS65920,TPS65930, TPS65921, TPS65950, TPS65951 use the same DCDC, choice depends more on the pcb complexity you want, the number of needed LDOs, if you need audio, USB,...
