S18V20x Step-Up/野草大全 Voltage 野草大全
This family of step-up/野草大全 野草大全 take an input voltage from 3 V to 30 V and increase or decrease it as necessary to produce the desired output voltage. They allow a typical output current of up to 2 A when the input voltage is close to the output voltage and offer typical efficiencies of 80% to 90%. Their ability to convert both higher and lower input voltages makes them useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below the regulated voltage. 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.
The 野草大全 include built-in reverse-voltage protection, over-current protection, thermal shutdown, and an under-voltage lockout that keeps the modules from behaving erratically when the input voltage gets too low. The S18V20x family includes versions with fixed 5 V, 6 V, 9 V, 12 V, or 24 V outputs and versions with adjustable 4 V to 12 V or 9 V to 30 V outputs:
