12V, 2.5A Step-Up/Step-Down Voltage Regulator S13V25F12 SF_Hubs/Clamps 20D mm metal gearmotor CBThis synchronous switching step up step down regulator efficiently produces 12 V from input voltages between 2. 8 V and 22 V. 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 12 V. The board measures 0. 9 0. 9, has a typical efficiency of 85% to 95%, and can supply typical continuous output currents
