The second power testing board turned up today, the TPS61220. Running this board with the CR2032 battery in the same configuration as the previous test, the board consumed 49uA. This is a little better than the LTC3525. This board also has an easy enable/disable switch. With the module disabled, the power consumption is 34uA; 6uA more than bare configuration. So, given testing, I think I'll go with this module. It's also half the price which is an added bonus.
