Frequently Asked Questions

Q: What does the TPS61023 Mini Boost Module do?

A: The TPS61023 Mini Boost Module is a step-up (boost) voltage regulator that takes a lower input voltage — such as from a single-cell Li-ion or LiPo battery — and converts it to a stable, regulated 5V DC output at up to 1A. It is widely used in DIY electronics, portable power supplies, and microcontroller projects.

Q: What safety protections does this boost regulator board include?

A: This board includes three key built-in protections: output short-circuit protection to safeguard connected devices, overvoltage protection to prevent excess voltage from reaching downstream components, and thermal shutdown protection which automatically disables the board if it gets too hot — helping ensure long-term reliability and component safety.

Q: What input voltage range does the TPS61023 Mini Boost Module accept?

A: The TPS61023 IC is designed to operate over a range typical of single-cell Li-ion/LiPo batteries (generally around 0.5V to 5V input). For precise input voltage limits and datasheet specifications, refer to the official Texas Instruments TPS61023 datasheet to confirm compatibility with your application.

Q: How do I connect and use this boost module?

A: The board features clearly labelled input (VIN, GND) and output (VOUT, GND) solder pads. Connect your lower-voltage power source to the input pads and draw your regulated 5V supply from the output pads. No additional components are required for basic operation — the module is ready to integrate into your circuit right away.
