Boost/buck/inverting regulator with adjustable output voltage, specifically designed to be incorporated in step down and step up and voltage inverting applications.
Q. Is it easy to connect this to a 3v dc motor? will it vary the voltage of it?
A. Hi Matilda. Thank you for your question. This will not be so simple as just connect to a motor - it can be used to control voltage output. You may be better with something like a voltage regulator.
