25W Step down adjustable switching regulator
The DE-SWADJ 3 is a larger version of our DE-SWADJ adjustable step down
voltage regulator. Previously it was necessary to put multiple DE-SWADJ
units in parallel to achieve ratings over 1A, which was bulky,
expensive and carried with it a considerable increase in dropout
voltage. The DE-SWADJ 3 is designed to be stronger, faster and better.
It can process 3A of current, typical ripple is 25mV and under ideal
circumstances the regulator can be up to 96% efficient.
It continues the ease-of-use of the DE-SWADJ,
making it simple to add an adjustable voltage source to a new or
existing project with all the efficiency benefits of switch-mode power.
The DE-SWADJ 3 is pin-compatible with the common 78XX family of linear voltage
regulators, and has a small screw on top that allows you change the
output voltage as your project evolves. It has integrated decoupling
capacitors, so external capacitors are not generally necessary.
DE-SWADJ3 can deliver a maximum of 25 Watts.
The screw potentiometer on DE-SWADJ is worm-gear driven, so small
vibrations and movement will not cause the voltage to shift. Use of
glue to hold the screw in place is strongly discouraged and could
damage the device.
