Pololu Adjustable 4-12V Step-Up/Step-Down Voltage Regulator S18V20ALV

Pololu Adjustable 4-12V Step-Up/Step-Down Voltage Regulator S18V20ALV

Regular price $0.00 $21.04 Sale

Key Features:

  • Input voltage: 2.9 V to 32 V
  • Output adjustable from 4 V to 12 V
  • Typical maximum output current: 2 A
  • Integrated reverse-voltage protection (up to 30 V), over-current protection, over-temperature shutoff, and under-voltage lockout
  • Typical efficiency of 80% to 90%, depending on input voltage, output voltage, and load

This powerful step-up/step-down regulator efficiently produces an adjustable 4 V to 12 V output from input voltages between 3 V and 30 V while allowing a typical output current of up to 2 A when the input voltage is close to the output voltage and offering typical efficiencies of 80% to 90%. Its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below the regulated voltage. The flexibility in input voltage offered by these regulators is especially well-suited for battery-powered applications in which the battery voltage begins above the desired output voltage and drops below the target as the battery discharges. Without the typical restriction on the battery voltage staying above the required voltage throughout its life, new battery packs and form factors can be considered.
