Pololu 9V Step-Up/Step-Down Voltage Regulator S18V20F9 Shipping:2-4 Weeks With this breakout board we'veThis powerful step up step down regulator efficiently produces a fixed 9 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
