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.

Some example applications include:

Powering 5 V or 3.3 V systems from lower-voltage batteries
Powering 5 V subsystems (e.g. sensors) in lower-voltage (e.g. 3.3 V) systems
Achieving consistent actuator operation when powered by fluctuating batteries
Powering high-brightness LEDs or a large number of LEDs in series

We also offer several boost regulators with fixed output voltages:

Pololu 9V Step-Up Voltage Regulator U3V12F9
Pololu 5V Step-Up Voltage Regulator U3V12F5
Pololu 12V Step-Up Voltage Regulator U3V12F12

Note: For high-volume applications, this product can be customized with fixed output voltages ranging from 2 V to 30 V.

Feature summary:
