Pololu Adjustable Boost Regulator 2.5-9.5V - PL-791 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 and the output voltage range is 2.5V and 9.5V (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.
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
