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. 2. Overvoltage and Thermal Shutdown Protection: Equipped with advanced safety features, the boost regulator includes overvoltage and thermal shutdown protection to prevent damage and long-lasting performance. 1. Output Short Circuit Protection: The mini boost module offers reliable output short circuit protection, ensuring your devices remain safe and secure during operation. 4. VIN VOUT Pass-Through Mode: 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: up boost module board ensures a true disconnect between input and output during shutdown, providing complete isolation and preventing any potential leakage or damage., Manufacturer: Akfldms
