Devices in the LED driver PMIC (Power Management Integrated Circuit) family are used to supply a current flow of controlled value to a load, typically a Light Emitting Diode, from a power source having a nominally fixed voltage. Key differentiators from the very similar products designed for voltage regulation include a characteristically lower feedback voltage (to improve system efficiency) and high prevalence of provisions for external control of the device\'s operating point, used to implement dimming functions in lighting applications.
