A step-down switching regulator can also be known as a DC-DC step-down regulator or buck converter device. These are a subclass of voltage regulators that decrease the voltage from an i/p to an o/p. This regulator uses a switch to separate a DC voltage and, after that uses a capacitor and an inductor to smooth […] The post MAX639 IC : PinOut, Features, Specifications, Circuit, Working, Datasheet & Its Applications appeared first on WatElectronics.com.
