TPS61023 Mini Boost Module 5V 1A Step-Up Voltage Regulator
TPS61023 Mini Boost Module – 5V 1A Step-Up Voltage Regulator
This compact TPS61023 Mini Boost Module is a must-have for electronics enthusiasts and makers. Despite being roughly the size of a linear regulator, it packs serious power-conversion performance — taking any input between 2V and 5VDC and delivering a stable, regulated 5V output at up to 1A. Perfect for battery-powered projects running on 2–3 alkaline cells or a single lithium cell.
Made in Mainland China.
Key Features
- Output Short-Circuit Protection: Built-in circuitry keeps your connected devices safe if an accidental short occurs at the output.
- Overvoltage & Thermal Shutdown Protection: Advanced safety mechanisms automatically shut the module down if voltage or temperature exceeds safe thresholds, protecting both the module and your project.
- Automatic PFM Operation for Light Loads: Automatically switches to Pulse Frequency Modulation (PFM) mode under light load conditions, maximising efficiency and extending battery runtime.
- VIN > VOUT Pass-Through Mode: Seamlessly transitions to pass-through mode when the input voltage already exceeds the output voltage — no interruptions, no hiccups.
- True Input/Output Disconnect at Shutdown: Ensures complete isolation between input and output when the module is shut down, eliminating leakage currents.

Frequently Asked Questions
Q: What input voltage range does the TPS61023 Mini Boost Module support?
A: The TPS61023 boost module accepts an input voltage range of 0.5V to 5.5V, with a minimum startup input voltage of 1.8V. It is ideal for 2–3 alkaline cells or a single lithium cell, converting that input to a stable 5V output.
Q: How much current can the 5V boost module deliver?
A: The module delivers up to 1A of output current at 5V. The 3.7A valley switch current limit ensures efficient and stable power delivery even under varying load conditions.
Q: Does the TPS61023 step-up module have any built-in safety protections?
A: Yes. The module includes output short-circuit protection, overvoltage protection, and thermal shutdown protection. It also provides true input/output disconnect during shutdown to prevent leakage, making it safe for use in sensitive battery-powered electronics projects.
Q: What is PFM mode and why does it matter?
A: PFM (Pulse Frequency Modulation) mode is automatically activated under light load conditions. It reduces switching activity to improve energy efficiency, which is especially beneficial in battery-powered applications where extending battery life is a priority.
