DC to DC Buck Converter 12v 24v to 3.7V 20A Step Down Voltage Reducer This fixedoutput buck converter provides a reliable 3.7V DC rail from a 12V to 24V input. It is designed for use in automotive, industrial, and hobby projects where a steady 3.7V supply is required and up to 20A of current may be needed. Key benefits Delivers a regulated 3.7V output from 12V to 24V input, enabling a single voltage source to power 3.7V devices. current capability up to 20A supports demanding loads and batterypowered equipment. Fixed 3.7V output simplifies integration and reduces the risk of overvoltage on sensitive components. Compact module design suitable for space constrained installations in vehicles, fixed installations, and portable setups. Improves system efficiency by converting excess source voltage rather than using a linear regulator.
