I'm using a TLV61220 IC boost converter to get 3.3V from a 1.5V AAA battery. I've built the circuit as specified on the datasheet (p. 1 of http://www.ti.com/lit/ds/symlink/tlv61220.pdf) with R1 at 1MΩ and the appropriate value for R2. The converter outputs 3.3V as expected with a small load, but appears not to be able to handle loads that draw more than a couple of mA (the output drops to about 1.8V with a 1K load, for example). The battery should of course be capable of supplying much more current than this, and figure 3 on p. 7 of the datasheet suggests that the converter should be too.
I was wondering if this sort of performance is to be expected given that the prototype circuit is on a solderless breadboard (and that the TLV61220 is hooked up via one of the crappy SOT-23 to DIP converters sold by Digikey). I've read that high frequency circuits do not perform well on breadboards, but I'm unsure whether it's plausible to put the extremely poor performance down to this factor alone. On the other hand, if the circuit was not hooked up correctly, then it seems unlikely that I'd be getting 3.3V output with small loads.
(I've tried with two different TL61220s with exactly the same results.)
