1 The S9V11x family has a minimum start-up voltage of 3 V, but it can operate down to 2 V after startup.
S9V11x step-up/step-down regulators can output voltages higher, equal to, or lower than their inputs at up to 1.5 A. Output voltages range from 2.5 V to 9.0 V, input ranges from 2.0 V to 16 V (with some limitations). Adjustable versions feature multi-turn trimmer potentiometers.
S18V20x step-up/step-down regulators can output voltages higher, equal to, or lower than their inputs. They can deliver up to 2 A when the input voltage is close to the output. Output voltages range from 4 V to 30 V, input ranges from 3 V to 30 V.
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.
The S7V8F5 switching step-up/step-down regulator efficiently produces a fixed 5 V output 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 of the input voltage range.
This switching regulator uses the SEPIC topology to produce 5 V from input voltages between 2.5 V and 18 V. The wide input range coupled with 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 compact (0.4″ × 0.575″) module can supply over 400 mA in typical applications.
This switching regulator uses the SEPIC topology to produce 9 V from input voltages between 2.5 V and 18 V. The wide input range coupled with 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 9 V. The compact (0.4″ × 0.575″) module can supply over 300 mA in typical applications.
This switching regulator uses the SEPIC topology to produce 12 V from input voltages between 2.5 V and 18 V. The wide input range coupled with 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 12 V. The compact (0.4″ × 0.575″) module can supply over 200 mA in typical applications.
