TPS61023 Mini Boost Module 5V 1A Boost Regulator Booster Board Voltage Step Up Boost Module Board from 2-5VDC to 5V TPS61023 Mini Boost Module 5V 1A Boost Regulator Booster BoardStep Up Boost Module Board Voltage Step Up Module From 2-5VDC To 5V Feature: 1. Output Short Circuit Protection: The mini boost module offers reliable output short circuit protection, ensuring your devices remain safe and secure during operation. 2. Overvoltage and Thermal Shutdown Protection: Equipped with advanced safety features, the boost regulator includes overvoltage and thermal shutdown protection to prevent damage and ensure long-lasting performance. 3. Automatic PFM Operation Mode for Light Loads: The booster board automatically switches to Pulse Frequency Modulation (PFM) mode during light loads, optimizing efficiency and extending battery life. 4. VIN>VOUT Pass-Through Mode: The step up module seamlessly transitions to pass-through mode when the input voltage exceeds the output voltage, maintaining consistent performance without interruption. 5. True Disconnect Between Input and Output During Shutdown: The step up boost module board ensures a true disconnect between input and output during shutdown, providing complete isolation and preventing any potential leakage or damage. Specification: Origin: Mainland China Type: Module Description This little board comes in handy whenever you need a lot of 5V power. It's about the size of a linear regulator, but it's actually a mini booster! Put 2-5VDC in one side and get 5V, up to 1A, out the other. Perfect for battery powered projects using 2 or 3 alkaline cells or a single lithium cell.
