I'm using this: https://www.sparkfun.com/products/10255 ... fgodAHIAmA
Why is this called a booster instead of a buck/boost converter? The datasheet (https://www.sparkfun.com/datasheets/Pro ... s61200.pdf) also refers to it in the headline as a boost converter even though it is written that it automatically transitions to a down conversion mode. How is this IC different than one that is called a "buck-boost converter" like this: http://www.ti.com/product/TPS63024/technicaldocuments
I assume the undervoltage lockout value of 2.6V was chosen because it's not good for li-po or li-ion batteries to be discharged lower than that. I understand that Vout is disabled during undervoltage lockout, but if the IC is still functioning, couldn't that current drain the battery more? Is it necessary to put the IC into shutdown mode with the EN pin? I saw the EN pin on the datasheet, it doesn't look like it's accessible on this breakout board.
