The LM2577S LM2596S Automatic Buck-Boost Power Module is a versatile DC-DC converter designed to automatically step up (boost) or step down (buck) input voltage to a stable output. Using the LM2577S boost converter and LM2596S buck converter together, the module seamlessly adjusts output voltage regardless of whether the input is higher or lower than the desired output. It is ideal for battery-powered systems, DIY electronics, portable devices, vehicle applications, and regulated DC supplies.
