Voltage Regulators - DC DC Switching Regulators

Products in the DC-DC switching regulator PMIC (Power Management Integrated Circuit) family are component-level devices used in applications requiring stabilization of a DC input voltage and/or transformation thereof to an output voltage of different magnitude. They are distinguished from similar products called "controller" PMICs by virtue of integrating the main switching element through which the power delivered by the device passes.
