This DCDC buck converter module steps an input voltage in the range 8V to 36V down to a regulated 3.3V output. It is designed to provide reliable 3.3V power for electronics from higher voltage rails such as 12V automotive or battery supplies, industrial power rails, and other sources within the specified input range. The module delivers up to 3A, making it suitable for powering 3.3V logic, sensors, microcontrollers, and other compatible devices. Key benefits Wide input range 8V to 36V enables operation from multiple power sources, including 12V systems and other supplies. Output up to 3A at 3.3V supports common 3.3V devices such as microcontrollers and sensors. Buck regulation provides efficient DCDC conversion, reducing heat compared with linear regulation for similar loads. Compact module form factor allows easy integration into projects, boards, enclosures, and wiring harnesses. Simple wiring and plugandplay integration enable quick deployment in a wide range of applications. Stable regulation across varying input voltage and load within the specified range supports dependable system performance. Key attributes Functionality: DCDC buck converter module with input 836V and output 3.3V up to 3A. Compatibility: suitable for 12V and other voltage rails commonly encountered in automotive, industrial, and batterypowered systems; designed to supply 3.3V devices. Size/Form factor: compact module suitable for inclusion in projects and limitedspace installations. Construction: module built to provide a practical 3.3V power solution from higher voltage inputs. Performance: delivers up to 3A at 3.3V with regulation that remains stable under varying input conditions and loads within the defined range. Applications Automotive and vehicle electronics: power 3.3V logic and peripherals from a 12V automotive system. Robotics and embedded projects: run 3.3V microcontrollers, sensors, and other peripherals from 836V power sources such as batteries or power supplies.
