Description
- LM3450AEV230V30, Evaluation Board is designed to provide an AC to LED solution for a 30W LED load. Specifically, it takes an AC mains input and converts it to a constant current output of 700 mA for a series string of 1 to 13 LEDs (maximum LED stack voltage of 45V). There are two assembly versions designed to operate from two different nominal AC input voltages, 120VAC or 230VAC. The board employs a two stage design with an LM3450A flyback primary stage and an LM3409HV secondary stage. The LM3450A provides an isolated 50V regulated output voltage and a power factor corrected input current
