DE-SWADJ 10W Adjustable Buck Converter

10W Adjustable Buck Switching Regulator

The DE-SWADJ is an adjustable version of our SW0XX series step-down voltage regulators. It is designed as the simplest possible way to add an adjustable voltage source to new or existing projects with all the benefits of switch-mode power efficiency. The DE-SWADJ is compatible with the common 78XX series linear voltage regulators and features a small screw on top that allows you to adjust the output voltage as your project evolves. It has built-in decoupling capacitors, so external capacitors are generally not required.

The DE-SWADJ can deliver a maximum of 10 watts.

The screw potentiometer on the DE-SWADJ is driven by a worm gear, ensuring that small vibrations and movements do not shift the voltage. We strongly advise against using adhesive to hold the screw in place, as it may damage the device.
