    Description

    The 12V Fixed Output DC-DC Buck Converter is a compact and reliable step-down power module designed to convert higher DC voltages into a stable 12V output. Built using an efficient BUCK topology, this module supports an input voltage range from 7V to 40V DC and provides a fixed 12V regulated output. Therefore, it is suitable for automotive, industrial, and embedded power applications where stable voltage regulation is required.

    The module can deliver up to 3A output current when additional cooling or a heatsink is applied. However, for continuous operation without extra cooling, 2A output is recommended to ensure stable performance and long service life. Its compact 32mm × 32mm size makes it easy to integrate into DIY electronics, robotics projects, camera systems, communication devices, and mobile power applications.

    Because of its wide operating temperature range (-40°C to +85°C), this buck converter performs reliably in harsh environments. If you need a stable 12V supply from a higher voltage source, this DC-DC converter module offers a simple and cost-effective solution. Featured By RoboticsBD.
