Pololu Adjustable 4-12V Step-up/Step-Down Voltage Regulator S18V20ALV
Manages input voltages from 3V to 30V
Ensures efficient power conversion up to 90%
Includes reverse-voltage and over-current protection
Features ENABLE pin for low-power state
Adjusts output voltage with a potentiometer
The Pololu Adjustable 4-12V Step-up/Step-Down Voltage Regulator S18V20ALV is a versatile device designed to manage input voltages ranging from 3 V to 30 V, adjusting them to produce an output voltage between 4 V and 12 V. This regulator employs a single-ended primary-inductor converter (SEPIC) topology, ensuring efficient power conversion with typical efficiencies between 80% and 90%. It is particularly suitable for battery-powered applications where the input voltage may fluctuate above or below the desired output voltage as the battery discharges.
This regulator is part of the S18V20x family, which includes both adjustable and fixed-output versions. It features built-in protections such as reverse-voltage protection, over-current protection, thermal shutdown, and an under-voltage lockout, enhancing its reliability and safety in various applications. The regulator can deliver an output current of approximately 2 A when the input voltage is close to the output voltage, making it suitable for a range of electronic projects.
The device is equipped with an ENABLE pin, allowing it to enter a low-power state, significantly reducing quiescent current. The output voltage can be adjusted using a potentiometer, and care should be taken to avoid contact with the potentiometer during measurement to ensure accuracy. The compact design includes multiple mounting and connection options, facilitating easy integration into different setups. Note: Ensure input voltage remains within specified limits to prevent damage to the regulator.
