[I.MX28] BATTERY POWERED APPLICATION

Hi all,

I made board that uses I.MX28.

In power part, i used "Battery powered application model" for decreasing I.MX28 heating. "VDD5V model" runs LinReg always. I think, it makes big heating. My board should operate at least 10 years nights and days.

 

Anyway, the problem is I don't want to use BATTERY for reducing the board cost.

What is happen if i remove battery in "Battery_powered application model"?

In this case, BATTERY and DCDC_BATT pin are floating. Does it make no problem?

And, in this case "VDD5V source only model" is the best way?


I really really appreciate to reading this.
