What is switching regulators?

Switching regulators are power converters that use switching devices (such as MOSFETs or BJTs) to efficiently convert electrical power from one voltage level to another. They operate by rapidly switching a transistor on and off, storing energy in an inductor or capacitor, and then releasing that energy to the output at the desired voltage. They are commonly used in a wide range of applications, including computer power supplies, battery chargers, and voltage regulation in electronic devices, due to their high efficiency compared to linear regulators.
