This powerful synchronous switching step-up/step-down regulator efficiently produces 5 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 5 V. The board measures 8.9 mm × 12.1 mm, has a typical efficiency of 85% to 95%, and can supply typical continuous output currents between 1 A and 2.5 A depending on the input voltage.
