I'm considering hiring an electrical engineer to design an emergency power supply for use in embedded devices. This power supply only needs to hold ~15 seconds of charge (enough time to safely shut down the devices). I would like to support 12V and up to 2A. Juice4Hault produces a [Supercapacitor UPS][1], but thier prices are very high. Batteries aren't reliable since they degrade and corrode over time.

I found some cheap parts that I hope will keep production costs low:

[2.7V 100F Supercapacitors ($1.50 each)][2]

[LM2623 ($0.50 each)][3]

Basically I would like to use low voltage supercaps and a voltage booster to convert extra amps into higher voltage output. Where I'm lost is interpreting the LM2623 datasheet. Could it reliably boost these Supercaps into 12V 2A 15-second output?

UPDATE:
I'm considering using two capacitors in series. Then I'd have **5.4V 50F** at my disposal. The [Samwha Green-Caps][4] that I am considering can pull 5A continuous current. So 5A ∙ 3V(Min) ∙ 80% efficiency = **12V ∙ 1A, sustainable for 10 seconds**, which I could live with. I would have to use a more expensive booster:

[TPS55332-Q1 ($2.50 each)][5]

**Is there an IC that can safely support this?**
