This 24V to 3.7V DCDC Buck Converter Module accepts an input in the 8V to 36V range and provides a fixed 3.7V output capable of delivering up to 3A. It is designed to step down a higher DC source to a stable 3.7V rail for 3.7V devices, with a compact module form factor that suits embedded projects and space constrained installations. While optimized for 24V systems, the input range supports a variety of applications including automotive, industrial, and solar powered setups. Key benefits Fixed 3.7V output up to 3A from a wide input range (8V–36V), enabling a simple power solution for 3.7V devices. Efficient buck regulation reduces heat and energy loss compared with linear regulators, improving system reliability in compact deployments. Compact module form factor for easy integration on a PCB or within an enclosure, making it suitable for hobbyist builds and professional projects. Straightforward integration with minimal external parts due to the fixed output configuration. Key attributes Functionality: DCDC buck converter module with fixed 3.7V output. Compatibility: Input 8V–36V DC; output 3.7V up to 3A. Size: Compact module form factor designed for embedding in projects and on boards. Construction: Standard PCB module using common surface mount components, suitable for quick integration. Performance: Delivers up to 3A continuous current to a 3.7V load from an input in the 8V–36V range. Applications and use cases Case 1: Power a 3.7V microcontroller and peripheral sensors in a 24V industrial control panel or other 24V systems, providing a stable 3.7V rail for reliable operation. Case 2: Convert higher DC supplies (12V, 24V, or 36V) to a fixed 3.7V rail to run Liion based devices or a small 3.7V electronics stack in a compact footprint. Case 3: Embedded projects and prototypes requiring a compact, fixed 3.7V source from a broad DC input range, enabling rapid development without a custom regulator design. Notes Ensure input remains within 8V–36V DC and that the load current does not exceed 3A. Adequate cooling or heat dissipation should be considered for continuous operation at higher current levels.
