LC5200 Series: Off-Line LED Driver ICs

The LC5200 series is a power IC, for non-isolated LED driver with commercial power supply applications, which includes both a main controller integrated circuit (MIC) and a power MOSFET. Its high voltage capability allows direct connection to a wide range of supply voltages ranging from 25 to 400 V (recommended). The LC5200 uses constant current mode to drive LEDs. The LC5200D series package is a fully molded DIP8 with pin 7 removed for greater isolation, and the LC5200S series package is an SOP8.
