Pololu Adjustable Boost Regulator 4-25V - PL-799 info
Pololu Adjustable Boost Regulator 2.5-9.5V 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. 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) and output voltage range is 4V to 25V. The integrated 2 A switch allows for output currents high enough to drive small motors, 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
