About the item

Input voltage: 2.7 V to 11.8 V.
Output voltage adjustable from 2.5 V to 8 V.
Typical continuous output current: 500 mA to 1 A across most combinations of input and output voltages.
Power-saving feature maintains high efficiency at low currents (quiescent current is less than 0.3 mA).
Integrated over-temperature and short-circuit protection.

The S7V8A sw step-up/step-down regulator efficiently produces an adjustable output between 2.5 V to 8 V from input voltages between 2.7 V and 11.8 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 the regulated voltage. The compact (0.45″ × 0.65″) module has a typical efficiency of over 90% and can deliver 500 mA to 1 A across most combinations of input and output voltages. The Pololu step-up/step-down voltage regulator S7V8A is a sw regulator (also called a switched-mode power supply (SMPS) or DC-to-DC converter) that uses a buck-boost topology. It takes an input voltage from 2.7 V to 11.8 V and increases or decreases the voltage to a user-adjustable output between 2.5 V and 8 V with a typical efficiency of over 90%. The input voltage can be higher than, lower than, or equal to the set output voltage, and the voltage is regulated to achieve the set output voltage. This flexibility in input voltage is especially well-suited for battery-powered applications in which the battery voltage begins above the desired output voltage and drops below the target as the battery discharges. Without the typical restriction on the battery voltage staying above the required voltage throughout its life, new battery packs and form factors can be considered.
