Pololu 15V 2.5A Step-Up/Step-Down Voltage Regulator S13V25F15 _MAKE_DISPLAY_ACC they can be signal orThis synchronous switching step up step down regulator from Pololu efficiently produces 15V 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 15V. The board measures 0. 9 0. 9, has a typical efficiency of 85% to 95%, and can supply typical continuous output
