LM2673SX-12 Application Field and Working Principle

As a part of the PMIC (power management IC) family, LM2673SX-12 belongs to the voltage regulator (VR) family specifically. This family of components is designed to control the voltages in a wide range of technologies ranging from computers to cars and even toys. The LM2673SX-12 belongs to the DC/DC switching regulators group, which means it uses pulse width modulation (PWM) to provide a stable, clean output based on the input voltage. This makes the circuit much safer and reliable than the traditional linear regulators.

General Application Field

The LM2673SX-12 is designed to be used in a wide range of applications. Its feature rich design makes it suitable for use in many types of devices from micro controllers to digital cameras and LCD screens.
