SparkFun LiPower Boost Converter

The LiPower board is based on the incredibly versatile TPS61200 boost converter. The board is configured for use with a LiPo battery, has solder jumpers for selectable 5V and 3.3V outputs, and features undervoltage protection at 2.6V. However, the board can also be used as a general protection device for a buck and boost regulator with an input voltage as low as 0.3V (the standard UVLO is 2.6V). With such a low input voltage and in sleep mode, the board also performs well in energy harvesting applications that utilize low input voltages.

Note: This board does not have reverse polarity protection, so please use the correct LiPo batteries or ensure to recognize the polarity when using your own input source.

Note: This product is a collaboration with Oleg from Circuits@Home. A portion of the sales goes back to them for product support and further development.
