The S7V8A switching 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.

Notes:

1
Without included optional headers.
2
When stepping down; current available when stepping up depends on input and output voltages (over 500 mA in most configurations).
3
While enabled (SHDN = HIGH) with no load. Actual quiescent current depends on input and output voltages.
