General Description
The MAX16841 is an LED driver for AC line (100V, 120V, 220V, and 230V AC) input lamps. It features proprietary control of the input current that allows lamps to dim smoothly from full to zero light intensity, while providing active power factor correction (PFC). It is a very flexible product that can be used in isolated (e.g., flyback) and nonisolated (e.g., buck) configurations. The conventional use of an optocoupler in isolated configurations can be avoided in MAX16841-based designs.
