This powerful, adjustable boost regulator can generate an output voltage as high as 25 V from an input voltage as low as 1.5 V, all in a small, 0.42" x 0.88" x 0.23" package. A trimmer potentiometer lets you set the boost regulator’s output voltage to a value between 4 and 25 V.
The Pololu adjustable boost regulator is a very flexible switching regulator (also called a switched-mode power supply, SMPS, or DC-to-DC converter) that can generate voltages higher than its input voltage. We offer two adjustable ranges: approximately 2.5 V to 9.5 V and 4 V to 25 V. The output voltage can be set using the trimmer potentiometer in the upper-right corner of the board. The input voltage range is 1.5 V to 16 V (the input voltage should be kept below the output voltage). The integrated 2 A switch allows for output currents high enough to drive small motors, as in our 3pi robot, and allows large voltage gains, such as obtaining 24 V from two NiMH or NiCd cells.
