Descripción
- AN-2098 LM3450 Evaluation Board is designed to provide an AC to LED solution for a 15W LED load. Specifically, it takes an AC mains input and converts it to a constant current output of 350mA for a series string of 1 to 14 LEDs (maximum LED stack voltage of 45V). There are two assembly versions designed to operate from two different nominal AC input voltages, 120 VAC or 230 VAC. The board employs a two stage design with an LM3450 flyback primary stage and an LM3409 secondary stage. The LM3450 provides an isolated 50V regulated output voltage and a power factor corrected input current. The LM3409 uses the 50V flyback output as its input and provides a constant current of 350mA to the LED load
