Pololu Pololu 6V Step-Up / Step-Down Voltage Regulator S18V20F6

The Pololu 6V Step-Up / Step-Down Voltage Regulator S18V20F6 produces a fixed 6 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.
