AC-DC Controllers & RegulatorsAC-DC controllers and regulators are power management ICs that are used to control and regulate the power supplied to an electronic circuit. AC-DC controllers and regulators are used in circuits that receive their power from an AC power source, such as the power grid, and convert it to DC power for use by the circuit. These ICs typically include a rectifier that converts the AC power to DC, and a control and regulation circuit that ensures that the DC power is supplied to the circuit at the correct voltage and current levels. AC-DC controllers and regulators are commonly used in power supplies for electronic devices, and in other applications where AC-to-DC power conversion is required.
