LM2577S LM2596S Automatic Buck-Boost Power Module (Solar Energy Step-down and Step- up Module) (RED)

The LM2596S & LM2577S DC-DC Adjustable Step-Up and Step-Down Power Supply Module is a high-performance buck-boost converter designed to efficiently regulate voltage for a wide range of electronic applications. This module can step up (boost) or step down (buck) voltage, providing an output voltage either higher or lower than the input voltage. Operating with remarkable efficiency—up to 95%—this DC-DC converter significantly reduces power loss compared to traditional linear voltage regulators. It’s ideal for powering devices that require a stable and adjustable voltage source. The input voltage range is 3.5V to 28V, and the output voltage range is 1.25V to 26V, making it extremely versatile. For instance, if your input is 5V, you can precisely adjust the output anywhere between 1.25V and 26V. The module supports a maximum input and output current of 1A, providing reliable performance for small and medium-power projects. This module integrates two powerful ICs—LM2596S (buck) and LM2577S (boost)—to offer dual functionality in a single board. It is compact, easy to use, and highly suitable for Arduino, robotics, LED lighting, DIY electronics, battery charging, and embedded projects. With its wide voltage adjustment range, stable output, and high efficiency, the LM2596S LM2577S converter is an essential tool for engineers, hobbyists, and makers who need a flexible power supply solution for their prototypes or lab setups.
