Pololu 12V 2.5A Step-Up/Step-Down Voltage Regulator S13V25F12 Brand_CodeBug You can drive the pinThis synchronous switching step up step down regulator from Pololu efficiently produces 12V 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 12V. The board measures 0. 9 0. 9, has a typical efficiency of 85% to 95%, and can supply typical continuous output
