Hi,
I'm trying to generate a 5Volts power supply from 3.7Volts LIIO battery by using the Booster TPS6122 http://www.ti.com/lit/ds/symlink/tps61220.pdf
obtained result:
- without load: I have Vout=5Volts
- ISSUE: when the circuit is loaded (10mA and more) the Vout voltage drops (from 5Volts to less than 4Volts).
I used the circuit as indicated in datasheet:
have you any idea why it doesn't work correctly !
