Powershield... LTC3525 vs TPS61220

[doublec4]

Hi all,

I was looking at modifying the powershield design to fit my needs... single CR2032 battery to operate my moteino @3.3V as a remote control with 2 buttons.

I noticed that REV1 started with the TPS61220 and then REV2 and beyond switched to using the LTC3525. What would be the main reason for the change? LTC3525 can support more current? I'm just wondering if it is worth it for me to use the LTC chip as it is much more expensive.

Thanks!

It never was the TPS, except in trials. I decided on the LTC since it's a much better chip IMO, more stable and higher current.
