Product description
>The DE-SWADJ 3 is a larger version of our DE-SWADJ adjustable step-down controller. Previously, it was necessary to connect several DE-SWADJ devices in parallel to achieve powers above 1A, which was bulky, expensive and associated with a significant increase in dropout voltage. The DE-SWADJ 3 is designed to be stronger, faster and better. It can handle 3A current, the typical ripple is 25mV and under ideal conditions the regulator can be up to 96% efficient.
It continues the DE-SWADJ's ease of use and makes it easy to add an adjustable voltage source to a new or existing project, with all the efficiency benefits of switching power supplies. The DE-SWADJ 3 is pin compatible with the popular 78XX family of linear voltage regulators and features a small screw on the top that allows you to change the output voltage as your project progresses. It has integrated decoupling capacitors, so external capacitors are generally not required.
The DE-SWADJ3 can supply a maximum of 25 watts.
The screw potentiometer on the DE-SWADJ is equipped with a worm gear so that small vibrations and movements do not shift the voltage. The use of adhesive to fix the screw is highly recommended and may damage the device.
Power: Adjustable from 3 to 13V output with screw
3A output at 3 to 8V
(See data sheet for rated current at higher voltages)
>90% efficiency
1.2V typical dropout voltage, maximum 2.0V at full load
