Frequently Asked Questions
Q: What does the TPS63802 Mini Boost Power Module do?
A: The TPS63802 Mini Boost Power Module is a compact DC-DC buck-boost converter that takes a wide input voltage (1.8V–5.5V) from a lithium battery or other source and delivers a stable regulated output of 3.3V or 5V at up to 2A. It's designed to keep your DIY electronics projects running efficiently, even as battery voltage drops.
Q: Is this module compatible with LiPo and Li-ion batteries?
A: Yes. The module is fully compatible with single-cell LiPo and Li-ion lithium batteries, which typically output between 3.0V and 4.2V — well within the 1.8V–5.5V input range. This makes it an excellent choice for portable and battery-powered maker projects.
Q: How does the TPS63802 chip extend battery life?
A: The TPS63802 chip uses a high-efficiency buck-boost topology with very low quiescent current, which means it wastes minimal energy during operation. By reducing energy loss and heat generation, the module draws less from your battery over time, effectively extending the runtime of your project.
Q: Can I use this module with an Arduino or Raspberry Pi?
A: Absolutely. The module's 5V output and breadboard-friendly pin layout make it a natural fit for powering Arduino boards, Raspberry Pi Zero, ESP8266/ESP32 modules, and a wide range of other microcontrollers and single-board computers directly from a lithium battery.
