PRT-10255: TPS61200 3.3 @ 200mA or 5V @ 600mA, 0.3 ~ 5V in

Summary

The LiPower board is based on the incredibly versatile TPS61200 boost converter. The board is configured to be used with a LiPo battery, has solder jumper selectable 5V and 3.3V output, and an under voltage protection of 2.6V. However, the board can also be used as a general purpose buck and boost regulator with an input voltage as low as 0.3V (default UVLO is 2.6V).

With such a low input voltage and quiescent current , the board also works well in energy harvesting applications that use low input voltages.

This board does not have reverse polarity protection, so please use 3.7 V LiPo batteries with the appropriate mating JST terminal or be sure to recognize the polarity if using your own input source."
