PRT-10255 LiPower Boost Converter for LiPo

PRT-10255 LiPower Boost Converter for LiPo: ultra-versatile!

Thanks to the built-in TPS61200 boost converter, and whatever the input voltage (from 0.3 to 5.5V), the PRT-10255 LiPower Boost Converter can act:

• either as a boost converter ensuring an under voltage protection of 2.6V;
• or as a buck-boost type regulator, capable of reducing or increasing the input voltage to achieve an output voltage equal to 3.3 or 5V;
• or as an energy harvester using a very low level of input current to power your projects.

Boost Converter for the LiPo battery: safety precautions

Because the LiPower is not reverse-polarity protected, it’s up to you as the user to make sure you don’t reverse the polarity of its LiPo battery: if you observe any suspicious battery swelling don’t hesitate to dispose of it, and beware of overheating as this can generate toxic gas emissions, or even cause a fire.
