Hello!
I'm an amateur hobbyist that came into possession of a pair of ultra-thin (0.5mm) LiPo batteries and decided to play with them to make a mobile phone charger. The batteries are very small, and only have a combined capacity of 90mAh, so I know it would do little more than tickle the phone's battery, but I also use a very old phone that has a miniscule 700mAh battery, so I would expect it to at least provide something.
Anyhow, I have wired up a TPS61072DDCR using 30 GA wire and a lot of patience, but when I check my output voltages, I do not get the 5V, 600mA output I was expecting. I've used the following components around the chip, notated the same way as the Online Datasheet:
C1 = 1x 4.7uF from Murata: 
C2 = 2x the same unit as C1, in parallel
L1 = 4.7 uH from Taiyo Yuden:
R1 = 1.62Mohm:
R2 = 180Kohm:
When I put it all together I had no issues that I could find with my multimeter, and no shorted circuits. Not sure if this is helpful or not, but here's a picture of my circuit:
Would you be able to let me know what I'm doing wrong? Thanks!
